Automatic Mesh Generation of Triangular Meshes in Finite Element Analysis - Mesh Generation Considering Stress Concentration near Crack and Notch Tips -

摘要

In this study, we present triangular mesh generation method considering stress concentration near internal crack tip. The total number of nodes and elements affect the computational time, and it is desired that the location of nodes is distributed such that distribution of physical variables is appropriately expressed. In this study, we focus on the distribution of stress components near crack tip, and propose the automatic mesh generation method considering the stress concentration. In addition, the stress analysis using the finite element meshes obtained by the present method is carried out, and the stress distribution near crack tip is compared with that obtained by using the other meshes. Furthermore, the stress analysis for V-notched plate is carried out using the finite element meshes obtained by the present method.
