摘要：

A method is illustrated for the evaluation of the stress distribution ahead of a crack under Mode I loading, The method is based on the knowledge of the weight function, whose general properties are employed to derive an integral equation. The solution of this integral equation, having the stress distribution as the unknown function. is reached through a numerical technique. Comparison with theoretical solutions shows that the proposed method allows an accurate reproduction of the stress distribution for every distance from the crack tip. The possibilities offered by the use of the method in combination with local fracture criteria are discussed.
