在最一般的术语中，损害可以被定义为引入系统的变化，对该系统当前或未来的性能产生不利影响。这一定义中隐含的概念是，如果不对系统的两种不同状态进行比较，损害就没有意义，其中一种状态被假定为代表初始状态，通常是未受损的状态。本文主要讨论结构和机械系统的损伤识别问题。因此，损坏的定义将仅限于这些系统的材料和/或几何特性的变化，包括边界条件和系统连接的变化，这些变化会对该系统的当前或未来性能产生不利影响。
In the most general terms damage can be defined as changes introduced into a system that adversely effect the current or future performance of that system. Implicit in this definition is the concept that damage is not meaningful without a comparison between two different states of the system, one of which is assumed to represent the initial, and often undamaged, state. This discussion is focused on the study of damage identification in structural and mechanical systems. Therefore, the definition of damage will be limited to changes to the material and/or geometric properties of these systems, including changes to the boundary conditions and system connectivity, which adversely effect the current or future performance of that system.
