Two-parameter concept for anisotropic cracked structures

Abstract

For two-dimensional anisotropic elasticity the M-integral was evolved, in terms of the boundary element method serving for numerical determination of the T stress which represents a notable parameter for fracture evaluation of cracked solid bodies on top of the stress intensity factor. T-stress issues for the crack face pressure instances are employed as the reference solutions to infer weight functions, e.g. to obtain T-stress results for thick-walled cylinders weakened by an internal edge crack subject to any complicated loading. Some examples are demonstrated.
