Abstract : This document summarizes the work performed by the author and associates at Stanford on a new approach to the analysis and simulation of localization arising in inelastic solids that exhibit strain-softening response. In addition, the document describes new results pertaining to the extension of these ideas to the finite deformation regime. Such an extension will be exploited numerically in follow-up publications. The techniques described in this document lead to the systematic construction of numerical methods that completely eliminate the strong mesh dependence exhibited by conventional treatments of the problem.
