Next generation Computational Algorithms for the Virtual Testing of Military Systems for Survivability and Design Studies

We shall develop an advanced three dimensional simulation capability to compute penetration environments with high fidelity. The strategy will be to develop the next generation of solid mechanics high-performance solvers based on lagrangian formulationsand incorporating all the relevant physical phenomena including contact and friction, thermo-mechanical coupling high strain-rate and material failure. This strategy has been successfully used in other areas of interest to the Army such as High-performance simulations of blast-structure interactions . A key element of this strategy is to develop robust adaptive remeshing algorithms which enable the Lagrangian modeling paradigm and increase the fidelity of the simulations. We shall apply theresulting capability to the prediction of penetration environments of interest to the Army with emphasis on the design of structures of improved survivability. The proposed advanced simulation capability will be used in a variety of commercialapplications including applications to the manufacturing industry (high-speed machining, explosive forming, extrusion forming and others) and new applications in the area of bio and nano technology with special emphasis on mechanical design of nano-scalebiodetectors.
