Numerical Simulation of Dislocation Climb in Crystalline Materials
Project Description

Dislocations are line defects in crystals and play crucial roles in plastic deformation processes. In the
climb motion of dislocations, they absorb vacancies that diffuse in the bulk of the material. This project
aims to examine the influence of the elastic effect in this dislocation climb process. The student is
expected to find exact or approximate solution of the vacancy diffusion equation with elastic effect in two
dimensions.
