Stress intensity factors and crack propagation path under mixed mode conditions

Use of crack propagation principles based on SIFs (stress intensity factors) is among the most common methods of fracture mechanic engineering. SIF is an important parameter in fracture analysis. In analyzing elastic fracture, SIF reveals the stress near the crack tip and substantial information abo...
