Test Cases in cylinder code

ill Ryu and Wei Cai

This tutorial describes test cases to check if cylinder code works well, especially for the image stress calculation. We provide Matlab files which generates ParaDiS inputs and plot the results. The theoretical background is published in Computing Image Stress in an Elastic Cylinder, Journal of the Mechanics and Physics of Solids, 55, 2027 (2007).

TEST1 : Straight edge dislocation along the cylinder axis

In the first test case, image stress of a straight edge dislocation is considered, as shown in the Figure 1.
