| 摘 要： | 本文基于连续介质损伤力学方法,通过引入伴随变量,讨论了损伤测量参量的选取对多机制损伤的测量以及建立损伤演化方程的影响。并从理论上证明了、实验上验证了采用单参量测量多机制损伤只能精确到同格损伤状态程度。由此指出了目前在连续介质损伤力学中广泛使用的损伤测量方法的局限性。

| Abstract: | Based on the continuum damage mechanics, the influence of damage measurment and damage evolution equations by selection of the damagemeasured parameter has been discussed by introducing accompanying vari-ables. Moreover, it has been proved theoretically that it can be only toaccuraies of the state of isotropy damage that single parameter is appliedto measure multimechanism damage. Thi conclusion is verified by experi-ment results. |
