摘 要: | 通过将升阶谱与有限条方法相结合,得到了以多项式级数为形函数的升阶谱有限条方法,并采用该方法对复合材料壁板结构在复杂边界条件下,受轴压、侧压及剪切载荷复合作用下的临界稳定性问题进行分析。数值算例结果表明,该方法综合了升阶谱和有限条的优点,可以快速稳定的精确求解复合材料壁板结构的临界失稳载荷。

Buckling Analysis of Composite Laminates Using Hierarchical Finite Strip Mehtod |
| |
Abstract: | Hierarchical Finite Strip Method (HFSM) can be obtained by hybridizing hierarchical and finite strip method, the shape functions of which are polynomial series. Then the buckling of composite laminates under complex boundary and load conditions are analyzed by HFSM. The numerical results illustrate that the HFSM combines the merits of both hierarchical and finite strip, and can be used for analyzing the buckling problems of composite laminates quickly and precisely. |
