Outline of lecture

The present course provides basic understanding of fracture of mechanical engineering structures.
The course deals with the basic mechanics of materials from the definitions of stress and strain in the
first lecture, and it includes outline of the linear fracture mechanics under the small scale yielding
condition. The linear fracture mechanics is indispensable for mechanical engineers to prevent
failures due to crack growth. Applicants should have attended the Advanced Course of Mechanics of
Materials.
