Parametric Study on an Improved Mesh-Free Crack Analysis Technique Using Singular Basis Function

특이기저함수를 사용한 개선된 Mesh-Free 균열해석기법에 대한 파라메타 연구

Previously, an improved crack analysis technique based on Element-Free Galerkin Method (EFGM) which includes a discontinuity function and a singular basis function was presented. The technique needs neither addition of nodes nor modification of the model, but it shows some dependency on the formulation and modeling parameters such as the class of weight function, the size of compact support, dilation parameter and the range controlled by the singular basis function. For those parameters, a parametric study was performed on the calculation of a discrete error and then, a guideline for the choice of adequate parameters in the technique was proposed.
