Lattice Defects & Mechanical Properties of Materials Lattice Defects & Mechanical Properties of Materials
講義概要
Lattice defects and their role on mechanical properties of solid materials are lectured. Topics such as linear elasticity (stress, strain, Hooke's law) and dislocation theory are included.
講義の目的
Concepts of linear elasticity (stress, strain, Hooke's law, etc.) will be introduced first. Then, lattice defects pertinent to understand mechanical properties of materials are discussed with emphasis on the dislocation theory.
講義計画
1. Introduction 2. Traction and stress 3. Distrotion and strain 4. Hooke's law and elastic strain energy 5. Lattice defects and dislocations 6. Stress-strain curves 7. Strengthening mechanisms
