Abstract

This paper deals with elliptical hole-crack problems in an infinite plate subjected to internal pressure by using a hybrid displacement discontinuity method (a boundary element method). Numerical results of the stress intensity factors (SIFs) are given. Especially, a few dimensionless parameters are introduced and it is illustrated using some examples that the dimensionless parameters have theoretically a guidance role for hole-crack design in an explosive engineering.

Keywords:
