| 中文摘要: |
| 基于Ｍｉｎｄｉｎ假定推导了考虑剪切的复合材料加筋层板的有限元列式，并在此基础上计算出筋间基板含嵌入分层以及筋与基板连接处含穿透分层的加筋层合板在受压缩载荷情况下的屈曲模式和临界力。本文所给出的有限元方法及结论对从事复合材料结构设计的工程人员具有参考价值。 |
| 英文摘要: |
| In this paper, a stiffened composite laminated plate element formulation is deduced, which is based on the Mindlin first order shear effect theory. A study of buckling behavior for the stiffened composite laminated plates with delamination damage under compressive loading is presented. Form numerical results and discussion of some typical examples, it is clear that the effects of the distribution of the stiffener, configulation, location and length of the delamination on buckling characteristic and mode are significant. The numerical method and conclusions provided in the paper are useful for engineers of composite structures. |
