The Comparative Analysis of the Non-Symmetric Thermal Shock Crack Propagation in Al2O3 and ZrO2 Bars
The aim of the paper is theoretical modelling and experimental verification of the nonsymmetric thermal shock crack propagation in compound ceramic Al2O3 and ZrO2. The theoretical problem formulation concerns the thermal shock problem in a strip or bar made of nonhomogeneous material, which can exhibit local fluctuation of its mechanical and thermal properties. Such approach allows for: analysis of the real non-homogeneous ceramic materials and solution of the composition optimisation problem for composite material with respect to thermal shock sensitivity. In particular the presented approach enables estimation of the stress intensity factors during thermal shock for any continuous composition of the ceramic material.
