An automated Peierls-Nabarro analyzer for dislocation core structure and slip resistance
Brief Introduction
PNADIS is a efficient program to analyze the property of dislocation of a crystal based on the Peierls-Nabarro model and its derived ones. It is dedicated to determine automatically the character and property of dislocation, including dislocation core structure, Peierls stress, pressure field around dislocation core and solid solution strengthening, for not only FCC and HCP structures but also complex crystals.
