✦ Synopsis

The standard specimen for meawring the crack opening displacement use5 a deep crack that provides a high hydrostatic stress. If a V notch. which produces a lower hydrostatic stress is substituted for the deep crack, then the initiation crack opening displacement is illcreased. Using both V notch bend and tension specimenh. it is shown that the initiation crack opening displacement is a function of the hydrostatic stress.

For the application of the weight function method the crack opening displacements for a reference case have to be known. An approximate method to derive the crack opening field from the stress intensity factor was proposed by Petroski and Achenbach [Engng Fracture Me&. 10,257 (1978)J. The limited ac
