One of the important requirements for the application of reduced activation ferritic/martensitic steelis to retain proper mechanical properties in irradiation and high temperature conditions. In order to simulate the impact toughness with the effect of temperature and irradiation, a simulation model based on energy balance method consisted of crack initiation, plastic propagation and cleavage propagation stages was established. The effect of temperature on impact toughness was analyzed by the model and the trend of the simulation results was basicly consistent with the previous experimental results of CLAM steels. The load-displacement curve was also simulated to express the low temperature ductile-brittle transition. The effect of grain size and inclusion was analyzed by the model. The transgranular-intergranular transformation in brittle materials was also simulated by the model.
