基于复合材料一维剪切理论—— Mindlin理论 ,给出了材料性质与温度有关的含分层损伤复合材料加筋和无加筋层合板的线性和非线性热 -机械力耦合情况下的屈曲问题有限元分析方法 ,并研究了含分层损伤的加筋和无加筋层合板的两种不同类型的热 -机械力屈曲问题。通过典型算例分析 ,讨论了热 -机械力耦合效应和分层大小对含分层损伤结构的屈曲性态的影响关系。 Based on the one-dimensional shear theory of composites-Mindlin theory, the buckling under the condition of linear and nonlinear thermo-mechanical coupling between stiffened laminates with temperature-dependent material properties and stiffened laminates Problem of finite element analysis, and studied two different types of thermo-mechanical buckling problems of stiffened and non-stiffened laminates with delamination damage. Through the typical example analysis, the effect of thermal-mechanical coupling effect and stratification size on the buckling behavior of delaminated structures with delamination is discussed.
