Asymptotic Elastic-Plastic Transition Stress of Shocked Crystalline Materials,

Abstract

An analysis of elastic-plastic shock yielding is presented. The analysis is based on the commonly accepted condition that the elastic-plastic transition zone is a heavily dislocated boundary. It is hypothesized that, at dislocation pile-ups at slip band intersections, the lattice can be momentarily cracked. It is shown that this condition allows an approximate determination of the asymptotic elastic-plastic transition stress. This transition stress is calculated with a plane-strain analysis of the localized inhomogeneous stress field about the incipient yield zone. (Author)
