Syllabus

Course Description

The course is designed to cover the following subjects: elasticity, continuum plasticity, micromechanics of deformation, dislocations and slip, basic strengthening mechanisms: strain hardening, grain size strengthening, solid solution strengthening, particle strengthening, micromechanics of fracture: brittle fracture, void initiation, growth and coalescence, ductile-brittle transition temperature, fatigue of materials, creep of materials.

 

Course Objectives

The aim of the course is to provide information about the elastic and plastic region deformation behavior of crystalline materials to applied forces, and to give students a fundamental theoretical background about the continuum description of stress and strain through crystalline and defect mechanisms of flow and fracture. In conjuction with the microstructural aspects of the plasticity it is  aimed to clarify the dislocation theory which will lead to a better understanding of plastic flow, strengthening mechanisms and fracture mechanics.
