SIFs of rectangular tensile sheets with symmetric double edge defects

Xiangqiao Yan, Baoliang Liu and Zhaohui Hu

Vol. 5 (2010), No. 5, 795–803
Abstract

Tensile sheets with symmetrically placed cracks on opposite edges are studied using the displacement discontinuity method with crack-tip elements. Three cases are considered: a rectangular sheet, one with half-circle indentations on the cracked edges, and one with notch indentations. Solutions for the stress intensity factors (SIFs) of the three problems are given, revealing the effect of the geometric parameters. By comparing the three cases, one observes that the indentations have a shielding effect.
