摘要：

In this paper, we consider a general integral expression for mode I stress intensity factor along the fronts of convex planar cracks. For this integral approximation, we develop a simple numerical quadrature formula on every convex set Omega which allows a precise estimation of the error. This permits the use of extrapolation techniques for the accurate computation of the integral. Copyright (C) 2002 John Wiley Sons, Ltd.
