Singularity characteristics for a lip-shaped crack subjected to remote biaxial loading

摘要

In this paper, the conformal mapping method wasadopted to solve the problem of an infinite plate containing acentral lip-shaped crack subjected to remote biaxial loading. Akind of leaf-shaped configuration was also constructed in orderto solve the problem. The analytical result showed that thesingularity order of the stress field at the tip of a lip-shaped crackremains - 1/2, despite the difference in notch-crack width.
