Doing More with Less: Pushing the frontiers of maximum strength with minimum weight.

Thursday, August 24, 2023 | Zoom Meeting Online 6:00 to 7:00 pm Pacific

Jens Bold, Boeing Research & Technology Europe, Munich

For decades, classical laminate theory has used linear material models to calculate stress in layered composite parts and then predict the structural load-carrying performance using a relatively simple failure criterion.  

Now, modern non-linear material models and applying modal based failure criteria can lead to better predictions of structural load-carrying performance. The resulting optimization gains—delivering the required strength with less material and weight—yield a lower CO₂ footprint in initial production, plus lower fuel cost and CO₂ in ongoing operation.  

In his online presentation, Jens Bold of Boeing Research & Technology Europe in Munich will take us through:

• The classical laminate theory methods,
• Newer validated methods to extract stress-strain curves as input for an advanced material model,
• Advanced modal based failure criteria for unidirectional and woven materials,
• Numerical methods with progressive failure analysis will be compared to standard linear methods for different types of numerical elements, such as 2D shell, 3D layered solid and 3D solid for each laminate layer,
• Validation for different element type specimens, including open- and filled-hole tension and compression, as well as compression after impact, and
• A comparison of the classical linear method using standard failure criteria with the advanced methods using non-linear material behavior and modal based failure criteria.

Join us at 6:00 pm PDT Thursday August 24^th to explore the frontiers of composite simulation that are being pushed back in the never-ending tradeoff between structural strength and structural weight.

About Jens

Following his initial training in aerospace engineering at Technische Universität in Munich, Jens Bold worked in automotive engineering companies in Munich, then moved into aerospace at Eurocopter in helicopter and aircraft doors development.

He then moved to Airbus working on fuselage and fin stress, with responsibility for 110 employees in three countries, and organizing worldwide composite training inside Airbus. In 2008 he moved back into automotive, joining the Toyota F1 team in Cologne. From there back to aerospace (and back to school) working with DLR (German Center for Air and Space Flight) aircraft wing design projects and starting his PhD thesis. He was then manager of new composites technologies at Johnson Controls, and later joined Boeing Research & Technology Europe in the new office in Munich in February 2016.

Jens received his doctorate in engineering in 2019, with thesis focused on developing the Cuntze-Bold failure and material model for composites. Since 2023 the Cuntze-Bold non-linear material model combined with Cuntze modal based failure criteria has been embedded in core MSC Nastran as MATCB (Cuntze-Bold). He is inventor or co-inventor on 28 patent filings relating to doors, windows, seats, fuselage beams, component joints and continuous fabrication methods.

His citation, from Pat Remy, PNWAIAA Council:

Our 2023 Industry Engineer of the Year, Roger Myers, is an experienced aerospace leader with over 30 years of experience. A few things to know about Roger. First, and of course, foremost, is he’s been in AIAA for 43 years, according to National, this upcoming September 1^st. Which means…he joined the beginning of his freshman year in aerospace engineering at the University of Michigan (I did the math…). And still here, at our Pacific Northwest AIAA awards banquet tonight.

After Michigan, Roger went straight east to Princeton for a PhD. From Princeton, next on his path from there to here, he went to NASA’s Glenn Research Center in the On-Board Propulsion Team leading research on advanced electric and chemical space propulsion technologies.

From NASA Glenn, Roger joined Aerojet Rocketdyne in 96. Over the first 10 years, he held positions as Executive Director, Systems and Technology Development and Director, Electric Propulsion and Space Electronics.

Then in 2006 he was named General Manager of Aerojet Rocketdyne’s Redmond Operations, and during his 4 years in this position, the In-Space Propulsion business doubled while earning excellent profits.

From there, he became Deputy Lead of Space and Launch Systems, then Executive Director of Electric Propulsion and Integrated Systems

Then, from 2013 to his retirement from Aerojet Rocketdyne in 2016, he was Executive Director of Advanced In-Space Programs, leading programs for next-generation space missions.

Since his retirement—if you really want to call it that—he’s been consulting to organizations on Space Systems and Technology, Strategy, Mission Architecture, Business and Program Management, Proposals and Education.

Along this path from AIAA freshman to tonight, he’s published over 100 papers on electric and chemical propulsion technology and in-space transportation architectures. And extended his aerospace leadership across an array of fronts:

• Since 2010, a fellow of AIAA; 30 years from that University of Michigan freshman signing up for the first time
  • 2014 winner of the AIAA Wyld Propulsion Award
• He’s served on multiple committees for the National Academy of Sciences, Engineering and Medicine, including being Co-chair of the consensus study on Space Nuclear Propulsion for Human Mars Exploration.
• The Electric Rocket Propulsion Society (ERPS): President from 2013-2020 (7 years)
  • On the Board of Directors
  • 2017 winner of their Stuhlinger Medal for Outstanding Achievement in Electric Propulsion
• The Washington State Joint Center for Aerospace Technology Innovation (JCATI): Chair from 2013 to 2022 (9 years)
• The Washington State Academy of Sciences (WSAS): elected in 2012
  • Which, for those of you not already familiar with it, is a working academy of 360 elected scientific and technical experts, focused on informing public policy and increasing the role of science in Washington state.
  • He was WSAS President from 2020 to 2022, navigating the disruptions of the pandemic, increasing member engagement, further building the organization and expanding programs, including a symposium on decarbonizing aerospace, agriculture, IT and communications in Washington State…I’ll come back with more about WSAS in a moment
• The Museum of Flight—our hosts tonight. On the Board of Trustees since 2015. With us tonight as Roger’s guest is the Museum of Flight’s CEO, Matt Hayes.
• Elected to the National Academy of Engineering 2022

I mentioned the Washington State Academy of Sciences. As you may have seen in email from us, Roger is chair of their upcoming WSAS Symposium in August on sustainable aviation, connecting the dots on technology, public policy, infrastructure and workforce development that are required for reaching the emission reduction goals for Washington State. We’ll be sending out more email announcements on this to our AIAA membership, so watch for those or head on over to the WSAS website. It’s something you won’t want to miss. Also with us tonight as Roger’s guest is Donna Riordan, the Executive Director of WSAS, and Professor Kristi Morgansen, chair of the UW aeronautics and astronautics department, who with Roger, are leading this important symposium.

Her citation, from the teaching colleague who nominated Mrs. Wommack:

Mrs. Wommack is the secondary school science teacher, teaching grades 7-12 in the Mansfield, Washington School District.

She is a veteran teacher with 17 years of experience and a constant seeker of professional development opportunities to bring new and fresh ideas back to her classroom. This summer, she will be participating in the second year of her Murdock research fellowship as well as traveling to the Space Coast for an NEH course about the history of space.

Previously, she has undergone professional development with UC Davis, Siemens, Honeywell, Army Outreach, U.S. Naval Academy, the Exploratorium in San Francisco, the Space Foundation, Yellowstone, NASA Glenn, NASA Wallops and the Columbia Scientific Ballooning Facility.

She believes that teachers have the summer off to participate in professional development and better themselves, and to that end has traveled to NASA Glenn twice for summer research, NASA Wallops for a rocketry workshop, NASA CSBF for scientific ballooning, San Francisco for a two week science phenomena workshop, Colorado Springs for a Space Across the curriculum workshop, and is a certified robotics instructor through UC Davis.

She is the advisor for our school’s STEM Club where she takes the opportunity to work with students in their areas of interest outside school hours. Students can be found coding robots, making 3D print projects, building electronics kits and many  other activities. She believes the time she donates to STEM Club is important to allow students the time to explore their own interests in science.

Following her Fund For Teachers fellowship, she has created a repository of virtual field trips and related materials which can be found online at a link I can give you if you’d like to have it. (https://laurie918.wixsite.com/sciberspace ). These materials are available to any teachers to use for free and she continues to add to it all of the time.

In addition, she has been a Space Foundation Teacher Liaison for several years and an active participant and advocate for space education. Her curriculum regularly includes inquiry-based lessons on rocketry, drones, coding, robotics and engineering, creating a top-notch science/STEM Curriculum for  our small rural school.

She has a master’s degree in Curriculum and Instruction with a STEM Emphasis and a NASA Endeavor STEM Teaching Certificate through a NASA Endeavor Fellowship. Her continuing education since becoming a teacher is extensive and goes wall beyond what is required to maintain her certification.

Mrs. Wommack has twice been a state finalist for Presidential Awards for Excellence in Mathematics and Science Teaching. She was the recipient of the INDEEDS—Industry’s Excellent Educators Dedicated to STEM—Award for 2018 in Idaho. She was a Fund for Teachers fellow in 2022, an NEA Global Learning Fellow in 2021, a Qatar Foundation International fellow in 2018 and a National Geographic Grosvenor Fellow in 2016. She also traveled to India as part of an American Councils fellowship in 2012. As part of her NASA Endeavor Fellowship, she was one of two fellows to be awarded a NASA summer internship through which she helped create an award-winning professional development for teachers. She has twice been named Teacher of the Year for the Mansfield school district. All of her fellowships have made their way back to her classroom, enhancing her story-telling approach which engages students in her science curriculum. Her students have been winners at state science fairs.

Mrs. Wommack has worked tirelessly to obtain grants to supply the Science Department with the best STEM materials and equipment available including rocketry supplies, robots, Arduinos, electronics kits and more, all at no cost to this small rural school. She leads the after- school STEM club and has created quite a zoo in the classroom, which is particularly engaging for the students. This has made her classroom a favorite in the school, especially the turtles which she rescued after they were abandoned and nearly froze to death. In addition, she volunteers to judge e-Cybermission, a U.S. Army-sponsored online educational science fair for students in grades 6–9, and has done so for several years as well as reading and scoring fellowship applications for Fund for Teachers, National Geographic and reading journal proposals for NITARP.

Teachers at small rural schools have few opportunities for recognition because there is a very small population of teachers and students who have the chance to see what they do. It would mean a lot to our school if Mrs. Wommack could be found deserving of this award.
