Thermal buckling analysis of moderately thick symmetric and antisymmetric laminates having simple supports and subjected to a uniform temperature rise and linearly gradient temperature variation through their thickness (linear temperature variation) is investigated in this study. Transverse shear deformation is taken into consideration by employing the first-order shear deformation theory (Reissner-Mindlin theory), and closed-form solutions of the critical buckling temperature are obtained. Numerical results show the effects of various factors such as temperature fields, stacking sequence, number of layers and plate aspect ratio on the critical buckling temperature. Moreover, the thermal buckling characteristics are clarified for the heat quantity and thermal force variation, which has an influence on the critical buckling temperature and buckled mode shapes for each temperature field.
