Computational Mechanics and Material Modeling
Abstract
Projects in this technical focus area develop physics-based computational tools, material models, and calibration and validation databases that support the design and development of weapon systems. These capabilities are intended to predict the complex phenomena across significant length (meso to continuum) and time (nano-seconds to minutes) scales. The tools will provide coupled, multi-physics and chemistry modeling capabilities that are scalable to massively parallel architectures for solving 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: 1) phenomenological or “discovery” experiments that provide the physics basis for model development, 2) experiments directly coupled to model development and application, such as characterization, calibration, and validation experiments, or 3) the development of advanced test methods or device development. The specific projects in computational mechanics and material modeling are: - CTH (Sandia code) shock physics and Sierra/Solid Mechanics (SM) codes & model development and supporting experiments. - Arbitrary Lagrangian-Eulerian Three-Dimensional (ALE3D) code and model development. - Composite case technology and modeling. - Dynamic properties of materials, modeling and validation. - Energetic materials and polymers under dynamic and thermal loading. - Fragment impact and response experiments.
