摘要：

In this paper, procedures for stress intensity factor computation using traction singular quarter-point boundary elements are discussed. Formulae that make use of either the nodal values of displacements or the nodal values of tractions of the traction singular quarter point boundary elements are presented. Comparison is made between the present formulae and the one by Raveendra and Banerjee that uses only the displacement at the quarter-point node. (C) 1997 Elsevier Science Ltd.
