• The mixed-mode fracture criterion of modes I and II of soda-lime glass was investigated using inclined indentation surface flaws in four-point bending. In order to examine the effect of mode II on the extension of cracks, specimens with inclined surface flaws oriented at an angle of 45゜with respect to the outer fiber tensile stress direction were fractured under hydrostatic pressure of up to about 100 MPa. The obtained catastrophic fracture paths were noncoplanar with the initial flaw plane. The values of the critical stress intensity factors, K_<IC> and K_<IIC>, were obtained with the ratio K_<IIC>/K_<IC>=1.06 observed. The experimental plots of K_IvsK_II were compared with the existing theories. A strain energy density fracture criterion best described the mixed-mode fracture.
