The results show that the stress intensity factor induced by the residual stress of an unloaded indentation crack is approximately equal to the fracture toughness. The applied stress or/and electric field, positive and negative, can cause propagating of the indentation crack, and the combined effect of mechanical and electric loadings corresponds to applying an efficient stress.
