Abstrakt: The local deformation near a crack tip were investigated when a cracked specimen was stressed beyond general yielding. Crack opening displacements, and near tip strains were measured by the moire technique. The gross elongation in the cracked-section was also measured. These three quantities were found to be linearly related to each other. Surface strain distributions near a crack are influenced by the local necking at the crack tip, which is controlled by the plate thickness.
