The stress intensity factor and stress field expression for long cracks near an infinite-length plate bore are calculated using the Muskhelishvili Complex Function Approach. It applies to engineered bore edge cracks, especially under the condition in which the elliptical bore is subjected to internal pressure or only the surface of the crack is subjected to internal pressure. The formula is validated by numerical simulation and applies both to elliptical and circular holes. The variation of stress intensity factor with crack length is analyzed when the special round hole is only subjected to internal pressure. It has practical application value in fracture engineering.
