【摘要】 对处于温度场中承受不同边界条件约束的矩形薄板进行应力分析和热屈曲分析 ,建立起关于平面温度应力的非线形偏微分方程 ,并应用五节点差分法对其进行求解 ,从而得出矩形薄板受温度场作用和相应边界条件约束时的应力分布特点更多还原

【Abstract】 This paper is about of thermal buckling problems of the thin rectangular plate,which is under a symmetrical temperature distribution.We set up non_linear differential equations and solved them.Stress results of thin rectangular plates are given, which solved thermal stress problems. We adopt five_node difference method to solve the thermal stress problem and the thermal buckling problem.更多还原
