Planning for the Study of Buckling and Postbuckling Response of Laminated Composite Beams

随着层合纤维复合材料结构元件的日益普及，需要对其力学性能进行有效的建模；特别是对它们的屈曲和后屈曲行为有一个完整的理解。这项工作将计划进行一项研究，重点是开发分析开放和封闭截面层压复合梁的局部、欧拉和弯扭屈曲模式的方法。将考虑剪切变形的影响。这些方法将用于截面单元由具有不同程度各向异性的矩形层合板组成的梁。//

As laminated fiber composite structural elements become more popular, their mechanical properties need to be efficiently modeled; in particular, that there be a complete understanding of their buckling and postbuckling behavior. The work will plan for a study focused on the development of methods for analyzing the local, Euler, and flexural-torsional modes of buckling in laminated composite beams of open and closed cross section. The effects of shear deformation will be accounted for. The methods will be developed for beams whose cross-sectional elements consist of rectangular laminated plates with varying degrees of anisotropy.//
