Generally, cracks that satisfy the energy condition run catastrophically. Three types of exceptions to this rule are described: ( 1) Stability occurs due to increasing rate of energy demand. (1) Stability of a lowet degree (neutral equilibrium) occurs when the energy reiease is independent of the cr

โฆ Synopsis
A simple criterion based on the engineers' theory of bending is suggested for the determination of the stability of fracture path in the compact tension test.
* Only 2 out of 11 specimens tested showed strong deviation of the fracture path from the centre line. In a further 3 specimens there was some tendency to deviate.

The path stability problem for fracture starting from a straight crack in a biaxially stressed plate is investigated. The analysis is performed by employing a simple equivalent crack in order to obtain an approximate evaluation of the Stress Intensity Factors of the S-shaped crack which may be gener
