alternating deformation meaning in Chinese

交变形变

Under varied loads such as cyclic and / or transient loading , soil structures or foundation will induce permanent and / or fluctuating plastic deformations . such plastic deformations are cumulative and / or alternating in nature with increase of time of loading during a sequence of cyclic loading . if the resulting accumulated deformations is limited within a given bound or the alternating deformations will be adapted to a given plastic state after a certain cycle numbers or a certain period of loading , the soils will be in shakedown state
在复杂变值荷载作用下，结构有可能出现两种状态：一种是在若干次载荷循环之后，塑性变形趋于稳定，在此后继的载荷循环中结构表现为纯弹性响应，这种状态称为安定状态( shakedown ) ；另一种则是塑性流动一直持续地发展或不断反复，直至结构破坏，结构的破坏有两种型式：一种是由塑性应变的累积引起的增量塑性破坏；一种是塑性变形多次反复引起的疲劳破坏，也称为交变塑性破坏。
