✦ Synopsis

The energy convergence of stress singular problems using the mixed finite element method is established. A mixed finite element method for determination of elastic crack tip stress intensity factor by energy release rate is also presented. It is shown through numerical examples that the mixed method has excellent potential for approximate analysis of stress singular problems.

## Abstract This paper is directed towards finite element computation of fracture parameters in functionally graded material (FGM) assemblages of arbitrary geometry with stationary cracks. Graded finite elements are developed where the elastic moduli are smooth functions of spatial co‐ordinates whi

A technique to evaluate the dynamic stress intensity factors and T-stress is developed by extending the scaled boundary finite-element method. Only the boundary of the problem domain is discretized. The inertial effect at high frequencies is modeled by a continued fraction solution of the dynamic st
