This paper is concerned with the theoretical treatment of a two-dimensional coupled thermal stress problem of an orthotropic material. In order to separate the coupled thermal and thermoelastic fundamental differential equations for the orthotropic body, we introduce a perturbation technigue for temperature and thermoelastic fields. Taking advantage of this technique, we can obtain the coupled thermoelastic solutions for the orthotropic body. As an example, we have analyzed the two-dimensional problem of an orthotropic thick plate due to symmetrical heating. And we have carried out numerical calculations for several values of thermal and thermoelastic orthotropic parameters. These effects on temperature and associated stress distributions are examined precisely.
