| Research Abstract |
Ductile fracture process is studied using Gurson's constitutive equation which considers nucleation, growth and coalescence of voids. Finite element analysis system, which can evaluate thickness effect and effect of mixed mode loading condition, is developed. Basic study on the mechanism of ductile fracture process is studied. Then this system is applied for the evaluation of interaction effect of multiple cracks in nuclear power plant structure. It is shown conservative evaluation is possible using this system. Results are presented in international and domestic journals. This system is shared in several research institutes for future application.
