Opening-Mode Stress Intensity Factors for Two Unequal Cracks at a Hole.

Abstract

An integral-transform method is used to solve the elastic problem of two collinear cracks at the edge of a hole in a sheet. Both uniform loadings on the sheet remote from the crack and loadings on the perimeter of the hole are considered. Since in all cases the loadings are symmetrical about the crack-line, only the opening-mode stress intensity factors are non-zero; these factors are calculated. An approximate procedure is examined for obtaining stress intensity factors for two cracks at a hole from that for one crack. (Author)
