โœฆ Synopsis

method is presented to derive the approximate weight functions, by using a new condition on the crack mouth, for edge cracks in the semi-infinite or finite plate under Mode I loadings. This method requires only one information, say, the reference stress intensity factor (SIF), K,. Numerical examples show that the present method is efficient in evaluation of the SIFs for edge cracks subjected to the polynomial loadings on the crack faces.

## Abstract In meshless methods, in general, the shape functions do not satisfy Kronecker delta properties at nodal points. Therefore, imposing essential boundary conditions is not a trivial task as in FEM. In this regard, there has been a great deal of endeavor to find ways to impose essential bou
