Elastic solutions for corner cracks undergoing uniform displacement-controlled loading

To understand the behavior of corner cracks involving displacement-controlled loading, the mode-I stress intensity factors and crack face displacements are determined for a quarter-elliptical corner crack undergoing uniform end displacement. A 3-D weight function method is used for the analysis. Various crack aspect ratios and crack-length-to-plate-height ratios are considered. The results show that the stress intensity factor and the crack opening profile for the uniform displacement-controlled loading can be significantly different from those for the uniform-stress controlled loading.
