Dislocation Mechanics

This lecture covers the mechanics of dislocations in materials, focusing on the movement and interaction of dislocations under stress fields. It explains the different types of dislocations, such as partial and mixed dislocations, and their impact on material properties. The lecture also delves into the concept of stacking faults, energy barriers, and hardening mechanisms induced by dislocations. Additionally, it discusses the role of obstacles in dislocation movement and the implications of dislocation interactions on material behavior.
