A constitutive model which considers both plastic deformation and solid–solid phase transformations has been developed for zirconium under high-rate loading. Within the multiphase mixture regime, a lower-bound (Ruess) or uniform-stress assumption i

Dynamic and quasi-static failure and dynamic incipient failure experiments were performed on a half-hard 10100 Cu material using several different specimen geometries, including uniaxial stress and several notches. An additional series of uniaxial st

Microstructures of metallic polycrystalline materials are varied and evolve with mechanical deformation. The influence of microstructure on mechanical behavior is discussed in the context of material model development. Several modeling approaches hav

A material strength model has been developed for the deviatoric stress of zirconium. The model takes into account different material properties for each phase and evolves separate yield surfaces for each phase. The strength model is coupled with a fr

HY‐100 steel is a material that behaves isotropically in the elastic and plastic region and acts anisotropically in failure. Since HY‐100 is a ductile metal, a more gradual failure process is observed as opposed to the nearly instantaneous failur

Our goal is to develop constitutive relations for the behavior of a solid polymer during high-strain-rate deformations. In contrast to the classic thermodynamic techniques for deriving stress-strain response in static (equilibrium) circumstances, we

The technique called Differential Sensitivity Theory (DST) is extended to the multi-component system of equations solved by the MESA2D hydrocode. DST uses adjoint techniques to determine exact sensitivity derivatives, i.e., if R is a calculation resu
