Physical Properties,ty ρ, specific heat C., density ρ, Young’s modulus . and Poisson’s ratio ν. These properties are not only important for material selection for a specific physical application, they also characterize the thermal shock sensitivity of ceramics.Mystic 发表于 2025-3-24 09:54:38
Fracture Mechanics,ts may be pores, cracks or inclusions. The brittleness of ceramic materials is caused by the low resistance against crack extension. The observed large scatter in strength is due to the scatter of flaw size in a component.机构 发表于 2025-3-24 11:49:54

Multiaxial Failure Criteria,ery often multi-axial stresses occur. Also under uniaxial external loading multiaxial stresses are possible, for instance in notched components. Rotating structures and components under internal pressure exhibit multiaxial stresses. Also thermal stresses are in general multiaxial. In this section, f
