根据Hasselman关于热应力断裂起始和残余强度之间密切关系的基本思想，在过去6年中，应用能量释放函数概念在理解热冲击方面取得了重大进展。一个令人满意的描述的不稳定和稳定阶段的裂纹扩展以及裂纹图案的形成是可能的。该理论还提供了一个理解的R曲线效应下的热冲击条件。热冲击行为是与应力场的形成相耦合的更大组的物理和化学结构变化的示例。对于这组现象，观察到一般行为的高度普遍性。
Following the basic ideas of Hasselman on the close relation between thermal stress fracture initiation and retained strength ,during the last 6 years significant progress has been made in the understanding of the thermal shock applying the energy release function concept. A satisfying description of the unstable and the stable stage of the crack propagation as well as of the crack pattern formation is possible. The theory also offers an understanding of the R- curve effect under thermal shock conditions. The thermal shock behavior is an example of a larger group of physical and chemical structure changes which are coupled with the formation of a stress field. For this group of phenomena a high degree of universality in the general behavior is observed.
