结构由于受到温度的作用,若其变形受到约束,就会产生受压的温度应力区;当温度升高达到一定数值时,会发生突发的屈曲而破坏;这就是结构的热屈曲问题.通常结构还会同时受到机械载荷等的共同作用,更增加了热屈曲分析的难度.目前,有关热屈曲分析的资料中,大多是几何形状简单的结构? Because the structure is affected by the temperature, if the deformation is constrained, a temperature stress region under pressure will be generated; when the temperature rises to a certain value, sudden buckling will occur and damage will occur; this is the thermal buckling problem of the structure. At the same time, the structure is also affected by mechanical loads, which increases the difficulty of thermal buckling analysis. At present, most of the data related to thermal buckling analysis are simple geometric structures.
