CALCULATION OF STRESS INTENSITY FACTORS AND FATIGUE CRACK PROPAGATION OF SEMI-ELLIPTICAL, PART-THROUGH SURFACE CRACKS

A method of analysis for semielliptical, part-through surface cracks in thick plates are presented. The finite element method involving a multilevel superelement technique is used for computation of stress intensity factors. The analysis procedure is based on the strain energy release rate, and the stress intensity factor is determined as a function of the crack geometry and the direction of propagation. The generality of the present approach allows it to be used for very complicated structures and complex loading conditions.
