Paul Du Bois has worked as an independent consultant in the field of industrial application of large scale numerical simulations since September 1987. He has specialized in the application of explicit integration techniques for crashworthiness and impact problems. Among Paul’s customers are most of the world’s automotive assemblers such as Daimler, GM, Ford, Opel, Fiat, Porsche, Volvo, PSA, Renault, Toyota, Nissan, Honda, Hyundai and many others including automotive suppliers and design and engineering companies. Paul’s more recent projects include a Daimler sponsored development of a generalized plasticity law for the simulation of plastics and the formulation of a tabulated hyper-elastic material law with damage for the simulation of rubber and foam. He was involved with the joint research organization of the German automotive industry, FAT, in the working groups: ‘Side Impact Dummies’ from 1992 through 1997 and ‘Foam Materials’ (1996 until 2009). In 2003, Paul was asked by LSTC to perform a training mission at the Russian national laboratory in Snezinskh.
Since 2004, he has also been a consultant to NASA and has worked on the space shuttle’s ‘return-to-flight’ program. In the field of defense applications, he is a consultant to Rafael in Haifa, Israel where he was involved in the simulation of mine blast problems and helicopter crash landings.
Paul Du Bois also teaches the LS-DYNA training classes Advanced Impact Analysis, User Material Implementation in LS‐DYNA, and Polymeric Material Modeling with LS-DYNA. He co-teaches, with Len Schwer, the LS-DYNA Explosives, Blast, Penetration, and Methods, Modeling & Simulation classes.
Len Schwer has worked in the area of defense applications where failure prediction is of primary interest, for the past 30 years; he had been a DYNA3D user since 1983 and an LS-DYNA user since 1998. His early work at SRI International included modeling the collapse of deeply buried tunnels under very high pressure loadings. While at Lockheed Missile and Space Company he worked on high speed earth penetrators designed to penetrate reinforced concrete structures buried in soil. He has worked with the US Navy to develop an analysis capability for predicting the penetration & perforation of metallic, concrete, and soil targets associated with improvised explosive devices (IED’s). He has a strong interest in verification and validation in computational solid mechanics, and is the past Chair of the ASME Standards Committee on Verification and Validation in Computational Solid Mechanics. Dr. Schwer is a Fellow of the American Society of Mechanical Engineers (ASME) and the United States Association of Computational Mechanics (USACM).
Len Schwer also teaches the LS-DYNA training class "Concrete & Geomaterial Modeling with LS-DYNA," and co-teaches, with Paul Du Bois, the LS-DYNA Explosives, Blast, Penetration, and Methods, Modeling & Simulation classes.
