In this section the subcritical crack extension below the high temperature regime is considered. The creep crack growth is described in Sect. 12.2. The subcritical crack extension under cyclic loading is dealt with in Chap. 6.作者: Microaneurysm 時(shí)間: 2025-3-22 13:25

Thermal Shock Behaviour,gradients only cause small plastic deformations, in the case of ceramics with its linear elastic material behaviour high stresses are generated. As a consequence, thermal stresses have to be avoided or at least to be minimized by an appropriate design or an appropriate material selection.作者: Crater 時(shí)間: 2025-3-23 00:45
