试验是针对各种不同的碳纤维增强塑料结构元件进行的。这些结构包括受压缩载荷的平板加强和未加强的壁板,受剪切载荷的平板和U型梁。本研究的主要目的是确定屈曲和后屈曲的特性,以及它们对于铺迭配置的依赖关系。采用干涉条纹的Moire法研究屈曲特性。 此外,用STAGSC代码对屈曲特性作理论研究。在所有未经加强的壁板的试验中,极限载荷总是超过屈曲载荷许多,而承受压缩载荷的经加强的壁板,其破坏载荷只稍高屈曲载荷。理论与试验结果表明两者是十分一致的。
The tests were conducted for a variety of different carbon fiber reinforced plastic structural elements. These structures include slab-reinforced and unswept slabs subjected to compressive loads, slabs subjected to shear loads, and U-beams. The main purpose of this study was to determine the characteristics of buckling and post-buckling, and their dependence on the configuration of the layup. Buckling behavior of Moire method using interference fringes. In addition, the STAGSC code is used to study the buckling behavior theoretically. In all unstimulated wall tests, the ultimate load is always more than the buckling load, while the reinforced wall subjected to compressive load has only a slightly higher buckling load. Theoretical and experimental results show that the two are very consistent.
