Fractures in the forms of joints and microcracks are commonly found in natural rocks, and their failure mechanism strongly depends on the crack coalescence pattern between pre-existing flaws. However, the crack coalescence pattern of rock specimens containing three or more flaws has not been studied

A model is proposed for prediction of fracture initiation from surface flaws, bands of slag inclusions and zones with low yield strength in thin-walled structures. The mod del applies to cases where the whole ligament or defect zone is plasticized. Application of the model to, esign cases requires i
