Tutorial 4 A 70 mm diameter bar is found to contain a a crack which is located circumferentially 8mm deep around the outer surface, and penetrating 8 mm deep. The bar is subjected to cyclic stress which varies from 40 MN/m? to 100 70 mm dia. MN/m?. Given that Kic=60 MN/m3/2 for the same environment, determine whether the crack will propagate to the failure.
