Investigation and Research into CAE Technique for Spot Weld Rupture (Part III)

摘要

The focus of this research is to establish the rupture criterion of spot weld. In previous report, the CAE model that could predict the Force-Stroke characteristic and the deformation mode about dynamic experiments of various spot weld joints is introduced. By using this CAE model, the relations between the stress field around spot weld and the rapture is discussed.
