摘要

The boundary element method is employed to obtain T-stress solutions for cracks emanating from a circular hole in finite rectangular plates. Numerical values of the T-stress are obtained using the M-contour integral approach. A range of crack lengths are analyzed for two hole sizes, and the cases of a single crack and double-cracks emanating front the hole in the plate under both uniform remote tension and simple bending are considered. For completeness, stress intensity factor solutions axe also presented. These results will be useful for failure assessments using two-parameter linear elastic fracture mechanics.
