摘    要: 针对激光束照射下承受轴压作用的圆柱薄壳,实现了材料参数(弹性模量E,泊桑比μ、线膨胀系数α)随温度变化情况下热屈曲破坏有限元数值分析。数值计算结果表明,激光照射区域产生的热应力和材料软化将导致处于正常工作状态的轴压圆柱壳发生灾难性的热屈曲破坏。

关 键 词:圆柱壳  激光  热屈曲

Abstract:A numerical model of the bifurcationthermo buckling failure of axially compressed cylindrical shell irradiated laser beam isestablished.The material physical properties,suchas Young smodulus,Poissons ratio and coefficient of thermal expansion,are changingwith temperature. So that the thermal bucklingbehaviour is actually nonlinear with respectto temperature. A corresponding computer program by using f
