An Analytical Model of Large Deformation Effects in Crystalline Aggregates.

Abstract

A microcontinuum model of (rate-independent) deformation in crystalline aggregates under macroscopically uniform, quasi-static loading is presented, corresponding to the general problem of instantaneous response from a deformed state. A rational discretization, which includes all convection and rotation effects at large strain, is fully developed, and questions of existence and uniqueness of solution are investigated through consideration of alternative quadratic programming problems equivalent to the governing equations.
