3. Course Objectives

This course will cover the basic theory of dislocation including fundamental concept of dislocation, basic linear elasticity, stress-strain fields and associated self-energies of dislocation. Dislocationin various crystal structures and its interactions with other defectstructures will also be given. The essential object of this course is to provide the students with the relationship between strengthening mechanism and dislocation motion in the crystalline structures in a comprehensive way.
