The tensile strength of brittle materials may be determined using a variation of equation 8.1. compute the critical crack tip radius for an al2o3 specimen that experiences tensile fracture at an applied stress of 275 mpa (40,000 psi). assume a critical surface crack length of 2 × 10−3 mm and a theoretical fracture strength of e/10, where e is the modulus of elasticity.
