Consider a crack arbitrarily oriented with respect to a stress field, as shown below: буу I. 0 = 0 oyx X 0₂ 0 xy 0 xx The stress state in the structure's coordinate system is d c [%] b mode II stress intensity factor in MPa/m? The crack length is 2a, where a = 8 mm, and its orientation is 0 = 2.52 rad. MPa, where d = 21, b = 12, and c = 3. What is the Note: Stress intensity factor is positive and thus you have to take the absolute value of relevant shear stress.
