Proposal on automatic triangular mesh generation method considering stress singularity near interface edge of bonded structure

Abstract

An automatic triangular mesh generation method considering the stress singularity near interface edge of bonded structures are proposed, and computational accuracy is evaluated by least square approximation. In addition, examination of inverse analysis for the order of singularity is also carried out. The finite element equation using the Akin singular element is employed in the inverse analysis of the order of singularity.
