Abstract

This paper deals with fracture analyses in three-dimensional bodies containing a surface crack. A general solution of stress-strain fields at the crack tip is proposed. Based on the stress-strain fields obtained, a high-order, three-dimensional special element is established to calculate the stress-intensity factors in a plate with surface crack. The variation of stress-intensity factors with geometric parameters is investigated.
