授業目標
In order to develop the insight into the mechanisms of the deformation and fracture of materials or structures, it
is important to understand those from micro-, meso- and macro-scopic viewpoints. In the recent development of
transport, furthermore, it has been necessary to know the dynamic behavior of materials with accuracy. In this
course, the metal materials are primarily treated within the fundamentals of the strength and fracture of
materials (dislocation, fractography, fracture mechanics, fatigue fracture, and so on) and the dynamic behavior
of materials (stress wave propagation, strain rate dependence, and so on), and the theory and practical
measuring methods of the dynamic characteristics of materials are focused on. Developing reading
comprehension and speaking in English is also aimed at.
