sample fails at a stress of 450 MPa, what isthe size of the largest surface flaw? Assume Y = (b) The same test is performed with a partially stabilized ZrO2 specimen. This material is transformation-toughened and has a KIc= 12.5MPa-Vm. If this material has the same flaw distribution as the fully stabilized sample, what stress must be applied to cause failure?
