Abstarct: On the basis of the steady-state two-dimensional theory of thermoelasticity, stress field and displacement around a hole in infinite anisotropic plate is discussed. The plate is subjected to uniform heat flux and material of the plate is assumed to be anisotropic, homogeneous and in this case, it is assumed that the plate has a linearly elastic behavior. The cutout is elliptical and it can be insulated condition or subjected to heat flux, along the hole boundary. The Lekhnitski complex variable method of anisotropic elasticity is extended to include the thermal effect. By means of conformal mapping for simplicity of using the Cauchy integral formula, the infinite area external to the elliptical hole can be represented by the area outside the unit circle. In this study, an attempt has been made to study the effect of different parameters such as fiber volume fraction, material properties, heat flux angle, the rotation angle of hole, the aspect ratio of hole size and fiber angle on the stress distribution and displacement around an elliptical hole. The results clearly demonstrate that in perforated plates subjected to uniform heat flux the stress distribution is also affected by aforementioned parameters.
