9309754 Shield 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.

随着层压纤维复合材料结构元件变得越来越流行，它们的机械性能需要有效地建模;特别是，需要完全理解它们的屈曲和后屈曲行为。 这项工作将计划的研究，重点是发展的方法，用于分析局部，欧拉和弯曲-扭转模式的屈曲层合梁的开放和封闭的横截面。 将考虑剪切变形的影响。该方法将被开发的梁的横截面元素组成的矩形层合板具有不同程度的各向异性。
