Question:
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 275MPa (40,000psi). 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.
