FEM Formulation and Analysis of Elasto-Plastic Stress Singularity

Abstract:

The present study shows a new idea for investigating characteristics of stress singularity field around a vertex associated with elasto-plastic properties of materials. FEM formulation for elasto-plastic stress singularity analysis is expressed to investigate an eigenvalue and the intensity of singularity.The elasto-plastic stress singularity in a flip chip joint was investigated using the FEM formulation. After that, the possibility of delamination on the flip chip joint was discussed.
