受热复合材料层合板的非线性静动态响应分析

Nonlinear Static and Dynamic Response Analysis of Heated Composite Laminated Plates

基于高阶剪切变形理论，突出考虑横向正应变和横向剪切应变的影响，对受热和外力联合作用下复合材料层合板的非线性静、动态响应进行分析。动态分析时计及了转动惯量的影响，给出了Ｃ°类有限元公式。文中数值算例同现有文献和三维有限元计算结果进行了比较，证明了本文方法的精确、有效性。文中还对层合反的边界条件、纵厚比及铺设角度对非线性动态响应的影响进行了分析。

The nonlinear static and dynamic response of composite laminated plates under the thermal and external combined loads have been investigated by the use of a high order shear flexible theory in which both the transverse normal strains and transverse shear strains are specially considered. The effects of rotational inertia are considered during the dynamic analysis. The C kind of FE formula is presented in the paper. The validity and effectiveness of the model are demonstrated by the comparison with the solutions in literatures and 3 D FEM results. The influences of boundary conditions, longitudinal depth ratio and stacking angle on the nonlinear dynamic response are studied.
