Course Title : Mechanical Properties of Solids and Fracture Mechanics

Code 31900 3rd year 2 No Restriction Lecture Japanese Assoc. Prof. Tsukada and Assoc. Prof. Murata,

Course Description

For crystalline materials such as rock and metal, macroscopic deformation behavior and destruction behavior is explained from the microscopic standpoint of fracture mechanicas and solid mechanics.

A quiz or a report problem is given in every class. The grade is evaluated by the sum of scores of the quiz or the report and the final exam. The grading weights of them are 30% and 70% respectively.

Course Goals

The goals of this course are to master the evaluation of elastic modulus of crystalline materials considering its anisotropy and to master the fracture mechanics for a crack containing material by estimating stress intensity factor, energy release rate and J integral. By taking this course, students can understand the elastic deformation and strength of the crystalline materials and the crack containing material.
