Abstract
A three-dimensional crack opening displacement correlation formula to calculate stress intensity factors is derived for 20-node collapsed is oparametric quarter-point elements. This formula has one order higher accuracy than the one usually used. Numerical results show that the ne w formula is insensitive to the variation of element size as compared to the old one for the finite element analysis of three-dimensional fr acture problems.
