Buckling Analysis of Discretely Stiffened Composite Curved Panels under Compression and Shear

摘要: 给出了一种复合材料加筋曲板压剪下的屈曲分析方法,分析中采用"板条有限元素法".文中针对复位移函数提出了一种改进方案,使运算可在实数范围内进行;还介绍了一种满足各类典型边界条件的简便处理方法.计算了一些实例,与现存的解符合较好.

Abstract: An analytical method for the buckling discretely thin-wall stiffened composite curved panels under compression and shear is presented by use of finite strip-element method.In the report a simplified scheme for complex displacement functions is developed.It enables that computation to be performed in real number algebra easily.And a simple and easy way to satisify the boundary conditions is introduced.Numerical results are given and are in good agreement with available data.
