Consider a brittle ceramic material that has an elastic modulus of 275 GPa and a specific surface energy value of 0.30 J/m. Would fracture be expected when a tensile stress of 5.0 MPa is applied if it is known that the critical surface crack has a length of 0.12 mm and tip radius of curvature of 7.5 x 10-3 mm? What maximum applied stress is possible without the expectation of fracture? i MPa
