Abstract

By using a hybrid displacement discontinuity method (a boundary element method), a center circular-hole crack in a rectangular tensile sheet is investigated in this paper. Detail numerical solutions of the stress intensity factors (SIFs) of the circular-hole crack are given, which can reveal the effect of geometric parameters of the cracked body on the SIFs. By comparing the calculated SIFs of the circular-hole crack with those of the center crack, the shielding and amplifying effects of the circular hole on the SIFs are found. The effects have perhaps an important meaning in engineering.
