Mechanical Behavior of Materials (I)

Course ID:  M720169P

Credits: 3

Objective: The subject of this course is very broad. The lecture teaches from the atomic point of view and extends to understanding the mechanism of solid deformation, and the principle of strength and toughness enhancement. Finally, the above fundamentals link to the mechanical behavior of structural materials in macroscopic view. The core teaching content includes the basic elastic mechanics, lattice defects, micromechanics, fracture mechanism, etc..

Course Prerequisites: Engineering Materials, Fundamental Elasticity, College Physics.

Outline:

1.Introduction 

2.Plastic deformation of single crystals 

3.Dislocation theory 

4.Strengthening mechanisms 

5.Fracture and fracture mechanics 

6.Tension test and flow properties 

7.Analysis of indentation

Teaching Method: 

Theoretical analysis, derivation, concept explanation with illustrations and data explanation. Oral presentations for postgraduate special topics.
