Theoretical, Experimental and Computational Studies in Plasticity.

Abstract

The following main results were completed during the previous grant period. A photoelastic technique to measure plastic flow and instability has been developed and measurements for shear band characteristics have been obtained. An innovative biaxial experimental apparatus for determining the evolution of the yield loci with plate specimens has been designed and manufactured. Constitutive models incorporating the effects of anisotropy, texture, material rotation, and inhomogeneity have been developed and successfully used to interpret available experimental data such as axial effects in torsion. Numerical evaluations for shear band and plastic instability problems have been performed resulting in new information about the effects of anisotropy and texture on the stability of plastic deformation.
