Analysis of stress singularity field near the cross point of inclusion and free surface by 3D element free Galerkin method(Influence of radius of curvature at vertex for stress singularity field）

摘要

In this report,we investigate variation of stress distribution and intensity of stress singularity near the cross point of inclusion and free surface based on 3D element free Galerkin method (EFGM).We especially focus on influence of radius of curvature at vertex for stress singularity field.As for computational model,silicon and resin bonded structure is employed.
