Proportional extrapolation techniques were proposed to compute simply and accurately stress intensity factors using the numerical computation method. They are based on procedures in which the effects of element division near the crack tip on stresses and displacements are corrected by comparison wit
A simple numerical method which allows calculation of Mode I stress intensity factors is presented. Using a linear extrapolation of the energy release rate 9, as calculated using standard nonsingular isoparametric elements and a relatively course mesh, accuracies of better than 5% may be obtained. T
