Reply to “Comment on ‘dislocation dynamics is chaotic”’

Abstract

We appreciate the interest of Ananthakrishna and Fressengeas [1] in the issues raised in Deshpande et al. [2]. Before replying to specific comments of Ananthakrishna and Fressengeas [1], we recapitulate the main points of our paper [2]. We carried out two-dimensional discrete dislocation simulations using the framework of Van der Giessen and Needleman [3] for tensile deformation of a plane strain strip and for mode I crack growth. The separation of nearby trajectories was measured by evaluating a norm kdk based on the positions of dislocations. Using this measure of separation we concluded that:
