| Abstract: | On the basis of compromise theory and general energy function,the paper proposes a simple and practical approach method for solving thermal expansion buckling problem in large deflection for an elastic columns. The formulas calculating critical change temperature and deflection are derived. The difference between nonlinear and linear solution are showed in this paper. |
