摘要：

An indepth examination of the effects of specimen motion on the technique of thermoelastic stress analysis is presented. It is shown that the presence of a non-uniform temperature distribution, coupled with the material motion due to cyclic loading, can greatly corrupt the measured data. This is particularly important when analysing composite materials in which heat is generated due to viscoelastic processes and/or to internal friction at delamination sites. A series of experiments using delaminated composite specimens as well as an externally heated specimen are presented to illustrate this problem and a mathematical model is developed to account for this phenomenon. Methods to remedy this problem are suggested and in the case of symmetrical conditions, it is shown that this effect can be effectively removed by appropriate post-processing of the data.
