摘要：

This paper presents simple approximate formulae for calculating the weight functions associated with cracks emanating from a notch under arbitrary loading. These weight functions are exact both for short cracks and for long cracks. A range of examples are presented to demonstrate the accuracy of the present method. (C) 2003 Published by Elsevier Ltd.
