Abstract

The standard specimen fur measuring the crack opening displacement uses 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 increased. Using both V notch bend and tension specimens, it is shown that the initiation crack opening displacement is a function of the hydrostatic stress.
