This is a graduate-level course in materials mechanics. The course provides a complete theory, which is generalized to three dimensional of the elastic behavior of materials, and applicable methods to design the structures and their members.
Students should be able to learn the basics of materials mechanics and applicable methods to deal with the behavior of solid objects subject to stresses and strains.

On completion of this course, the students should be able to:
Understand the theory of elasticity and a fundamental concept of fracture mechanics.
Calculate mechanical states of structures and estimate the strength of elastic bodies with cracks.

It is desirable that students attending this class are already interested in structural design and mechanics. Linear algebra and the basics of materials mechanics are requested in this class to solve engineering structural problems.

(15) Reviewing of the course

Less than D points is an indicator of failure.
Evaluation includes homework and reports of strength analyses. If students do not submit homework or a report, students will receive a grade of failure.

Feedback for students will be given when each report is returned and explained.

(5) Mechanics of Solids and Structures: Second Edition 2nd ed. Edition by DAVID W A REES (Author)

Friday 11:00-12:00 at Room No. 8-254 or 8-302 in Building 8

Material mechanics is one of the essential disciplines for the design of machines and structures. The course must be an opportunity to learn the fundamentals of the mechanics of materials.

Not applicable

As for practical experience, I was in charge of production/quality control and material development at a steel-making company.
