Abstract -This study presents a computational model for studying the mechanical effects of thermal shock over armour material used for fusion reactor. The simulation study comprises of transient thermal shocks over the bulk substance for a period of 1ms. Latter on the cracking behaviour is predicted by extending the virtual crack growth for screening out the efficacy of the used material and its composition. Â
