Abstract
Crack resistance is important to exam the structures destroyed under static and dynamic load as well as to the ceramic products under extreme mechanical and thermal load. But in addition to the metallic material, ceramic and ceramic composite materials have been pointed out as low resistance referred to a brittle materials form thermal impact. As destroyed ceramics are impossible to be restored, so the development of high toughness ceramics is required. To get high strength material design variables while keeping light weight, this study derives the modulus of elasticity for ceramic disk with elliptical crack pore and performs fracture behaviors assessment by applying the modulus of elasticity derived and MSST(Maximum Shear Stress Theory) techniques to compare with test data. As a result of assessment of fracture behavior based on the MSST, if stress is greater than fracture strength of material, it showed high probability of occurring of the shear fracture when fracture strength is 38 kgf.
