New solution algorithm for Volterra’s defects — •Jürgen Weidmann — keine

A new method is introduced in order to derive displacement fields with divergence-free stress tensors. Based on this method, we present an algorithm for fitting the solutions to different boundary conditions. We apply this algorithm to Volterra’s edge dislocation. We calculate the new displacement fields and the related strain and stress tensors corresponding to a crystal and a tubular cylinder. Finaly we present the computed fringe patterns expected by the photo-elasticity method.
