| 中文摘要: |
| 本文基于高阶剪切变形理论，考虑同天应变和横向剪切应变的影响，对受热复合材料层合板壳的非线性热动态响应进行分析，计及了转动惯量的影响，给出了通用性较好的Ｃ＾０类有限元公式，文中数值算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，文中还就层合板的边界条件、纵厚比及铺设角度对非线性热动态响应的影响进行了分析。 |
| 英文摘要: |
| The nonlinear thermal dynamic response of composite laminated plates is investigated in this paper by the use of a high order shear flexiable theory which can consider both the transvers normal strain and shear strain.The rotary inertia is considered also.The C 0 kind FE formula is given in the paper.The numerical results show that the validity and effectiveness of the model by comparison with the results available in literature and three dimmensional solutions.The effects of boundary conditions,longitudinal depth ratio and stacking angle on the nonlinear dynamic response are studied. |
