The Young's modulus and ultimate tensile strength of the most popular ceramic material, aluminum oxide or alumina (Al2O3) are 370 GPa and 300MPa, if it has zero porosity. (a) Determine the porosity of an alumina if its Young's modulus is measured as 325 GPa. (b) Determine the exponent n if the same alumina as in (a) is measured to have an ultimate tensile strength of 210 MPa

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. 0.37 nm 0.39 nm 0.319 nm 0.42 nm
