摘 要: 利用五节点差分法,在热屈曲应力分析的基础上,对处于温度场中的矩形薄板进行热屈曲分析,深入研究了矩形薄板厚度和屈曲临界温度应变值之间的关系,从而得出矩形薄板发生热屈曲时临界温度应变值与厚长比的平方成正比的结论. This paper made use of the five-nodes difference method, analyzed thermal buckling problems of the thin rectangular plate under a symmetrical temperature distribution, which is on base of thermal stresses problems' analyses. which is to-sides simply supported and clamped-clamped supported boundary conditions. studied the relation between thin rectangular plates' thickness and critical thermal strain values, draw a conclusion which is the Direct-proportion relation between Critical strain values and the double of thickness to length (h/a).
