概要
After Fukushima accident in 2011, demand in a design and management to predict severe accidents like Fukushima accident have been realized. To realize them, we must clarify fracture event of reactor pressure v essels or containment vessels. However, the mechanism of failure of structure under severe condition like overpressure or hyperthermia is not clear completely. If we can to predict damage or failure causing se vere accidents in advance by some method, we can take some measures retaining soundness of plant. In my research, as a first step, I will develop the method of measuring the deformation until damage or failure . I will perform a tensile test of metallic plate simulating a structure under ultimate load, film it with high speed camera and calculate deformation volume of plate by image analysis, i.e. template matching.
