Computational Mechanics and Material Modeling
Abstract
Projects in this technical focus area develop computational tools, material models, and calibration and validation databases which support the design and development of weapon systems. These capabilities are intended to predict complex phenomena across significant length (meso to continuum) and time (microsecond to minute) scales. The tools provide coupled, multi-physics and chemistry modeling capability that are scalable to massively parallel architectures for solving very diverse problems across the weapons systems’ research and development and acquisition communities. Numeric tools are the foundation that makes possible the integration of mechanics, materials science, physics, and chemistry. This focus area also includes an extensive experimental component consisting of phenomenological or “discovery” experiments that drive model development; calibration experiments to compliment models; and validation experiments for model and code validation. The specific projects in computational mechanics and material modeling are: – CTH, SIERRA code & model development and experiments – Arbitrary Lagrangian-Eulerian (ALE3D) code & model development and experiments – DUNE granular flow model development – Composite case technology and modeling – Near-field lethality modeling – Dynamic properties of weapon materials – Energetic materials and polymers under dynamic and thermal loading – Fragment impact and response experiments – Thermal battery performance modeling
