Effect of increasing disorder strength on crack nucleation: Simulations of system size of L_x = 8 μm, L_y = 0.5 mm, and L_z = 1.0 mm where D = 2.995, W = 0.125 mm, and (a) has a R_G of 0.05 (b) has a R_G of 0.2 (c) has a R_G of 0.8 where the disorder, stress and damage distributions are displayed (top, middle, bottom respectively)
