Notes:
The material characterization on the weak points of the structural systems is essential toevaluate safety accurately. However, general material characterization methods such as uniaxialtensile test and CTOD (crack tip opening displacement) test are destructive, therefore, it cannot beapplied to the system in use. To overcome this problem, the material characterization usinginstrumented indentation technique was developed. However, current researches on instrumentedindentation technique focus on the hardness measurement. The evaluation of flow property, residualstress and fracture toughness using instrumented indentation technique is not sufficiently performed.In this paper, we introduce the evaluation method of the flow property, the residual stress near theweldment and the fracture toughness developed from damage mechanics. The algorithm of flowproperty evaluation, the residual stress evaluation model and the fracture toughness model by usingindentation were verified comparing with the experimental results
