Abstract
To begin with, linear elastic behaviour is assumed to explicate the basic concepts of fracture mechanics, namely energy and stress intensity approaches. The respective terminology is introduced and the physical quantities of energy release rate and stress intensity factor are defined. Criteria for unstable “brittle” fracture based on the energy release rate and the stress intensity factor are established. Some analytical expressions for stress intensity factors of real structures are given and the problem of a cracked cylinder under internal pressure is addressed, in particular.
