Fundamentals of materials science and solid mechanics applied to selected subjects in
fracture, major topics include linear-elastic, elastic-plastic, and fully plastic fracture
mechanics, fatigue, creep rupture and creep crack growth and environmentally assisted
fracture. Emphasis shall be placed on relating the microscopic (continuum)
characterizations.
