In this paper the thermal buckling load of a curved beam made of functionally graded material (FGM) with doubly symmetric cross section is considered. By instability conditions we mean the in-plane and out-of-plane buckling. The stability equations are derived using the variational principles. The curved beam is under temperature rise for thermal loading. The solution for critical thermal buckling load is obtained using the stability equations and the Galerkin method. The critical thermal buckling load is obtained.
