Abstract

In damage-tolerant and structural-integrity analyses, the residual strength of a flawed component must be evaluated. For brittle materials, linear-elastic fracture mechanics (LEFM) concepts, such as plane-strain fracture toughness, KIc, are used. For materials that exhibit large amounts of plasticity at the crack tip prior to failure, LEFM techniques must be extended to incorporate new notions such as J-integral, CTOD, CTOA, R-curve and Ct-integral. Introduction of these quantities and the demonstration of their applications in materials and designs pertinent to the engineering fields will be the primary theme of these lectures.
