摘要: During thermal shock of ceramic materials crack propagation initial cracks leads to an increase in length. Therefore, the strength after is reduced from σ c f . This reduction can be described by application fracture mechanics methods [1]–[5]. The final length and thus depend on the size geometry component, the conditions (temperature component, temperature medium, heat transfer), physical properties material which influence stress distribution (thermal conductivity, expansion coefficient, capacity, density, elastic constants), mechanical material.
