基于高阶剪切变形理论(HSDT),采用C0有限元(FE)公式对层压复合材料斜扭壳进行自由振动分析。公式涉及横向曲率的影响。C0有限元公式已可以有效地解决C1在高阶剪切变形理论(HSDT)中的连续性问题。在当前由9个节点(每个节点包含7个未知参数)组成的模型中使用等参有限单元。由于在现有的文献中,对于高阶剪切变形理论对层压复合材料斜扭壳的自由振动问题并没有可用的研究结果,现有的分析结果经过了无倾斜角的层压复合材料扭壳以及层压复合斜板的结果的验证。通过不同的几何、边界条件、铺层方向和倾斜角介绍这一新分析结果。
Based on the high-order shear deformation theory (HSDT), the C0 finite element (FE) formula is used to analyze the free vibration of the twisted composite shell. The formula relates to the influence of lateral curvature. C0 finite element formula has been able to effectively solve the C1 in the high-order shear deformation theory (HSDT) continuity problem. An isoparametric finite element is used in a model currently consisting of 9 nodes (each node contains 7 unknown parameters). In the existing literature, there is no available research result on the free vibration problem of high-order shear deformation theory for the torsional torsional shell of laminated composites. The existing analysis results have been passed through the non-inclined laminated composite material Shell and laminated composite swashplate results of the verification. This new analysis is presented by different geometries, boundary conditions, lay-up directions and tilt angles.
