Abstract
Prediction of material behaviour under different loading situations involve a multifaceted concept of mechanics. To predict the material behaviour of the components operating under a radioactive environment such as that in nuclear power plant or in space applications, the effect of radiation should be accounted. Industrial steels components when exposed to radiation undergo radiation embrittlement, which is highly undesirable. The present work is aimed to predict the behaviour of industrial grade steel under monotonic and cyclic loading considering the effect of radiation load. The material behaviour under monotonic loading for non-irradiated and irradiated specimen is compared with the published experimental results. Further, the cyclic behaviour is predicted using the validated model to demonstrate the significance of incorporating the radiation hardening terms in the constitutive model to consider for the radiation hardening effect.
