A principal subject of the research program was the development of the anisotropic hardening theory of Stouffer and Bodner for elastic-viscoplastic materials into a practical computational tool. This has been achieved and demonstrated for problems of the dynamic impact of indenters into slabs of the reference material which experience induced plastic anisotropy. Another development has been the application of the elastic-viscoplastic constitutive equations with isotropic hardening to problems involving laminated materials. The equations have also been used as the basis to examine the response of metals over a wide range of temperatures and strain rates and as the material model in fracture mechanics problems.
