### 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.

### Grading

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.

### Course Topics

Theme | Class number of times | Description |
---|---|---|

Introduction | 1 | Overview of this course is presented, and then material testing method is simply explained. |

Structure of crystalline material | 3 | Basic form of space lattice of crystalline materials are lecutured, and then the indication method of each crystalline form is presented. |

Elastic modulus and theoretical strength | 3 | Elastic modulus of single crystal and crystalline material is lectured from the point of atomic bond form, and then theoretical strength of a material is explained from atom level. |

Fracture mechanics | 5 | Linear fracture mechanics and nonlinear fracture mechanics for a crack containing material are lectured. Stress intensity factor, energy release rate, J integral etc. are explained. Fracture in mixed mode is also explained. |

Mechanical model of composite | 1 | Mechanical models of composite such as Vogit model, Reuss model, and Eshelby's equivalent inclusion method are lectured. |

Rheology | 1 | Macroscopic rheology models are reviewed, and then microscopic rheology based on the Eyring's rate process theory is explained. |
