In the present work the local mechanical behavior and fatigue resistance of the welding material were investigated with help of the instrumented indentation technique in combining with FEM computations. By assuming a power-law strain hardening, the elastic-plastic properties of the welding material were identified from inverse indentation analysis with help of finite element simulation. A critical plane based Cruse-Meyer model was introduced to predict the LCF fatigue life of the weld joints. Combined with the critical distance concept, the fatigue life in center-holed specimens was investigated and verified with experiments.
