摘要

本文研究了双向功能分级材料（BDFGM）曲面夹层梁的稳定性和自由振动行为。考虑了材料成分沿切线方向和径向方向的同时变化。采用了基于 4 参数全局局部剪切变形理论的三节点曲线等参数梁元素。所获得的结果与文献中的结果进行了验证。考虑了各种参数，如长宽比、深宽比、梯度指数、边界条件等。提供了几个 BDFG 曲线梁的结果作为基准。

Finite element model for stability and vibration analyses of bi-directional FG curved sandwich beams

This paper investigates stability and free vibration behaviours of bi-directional functionally graded material (BDFGM) curved sandwich beams. Simultaneous variation of material compositions along tangential and radial direction is considered. A three-node curved isoparametric beam element based on a 4-parameter global–local shear deformation theory is employed. The obtained results are verified with those from literature. Various parameters such as aspect ratio, deepness ratio, gradient indexes, boundary conditions are taken into account. Several results of BDFG curved beams are provided for benchmark purpose.
