| 摘 要： | 本文采用摄动法,以中心挠度为摄动参数,研究了固定支承的正交异性椭圆薄板和叠层板在均布载荷作用下的大挠度弯曲。并以石墨/环氧纤维增强复合材料为例对各种长、短轴比值F的薄椭圆板和对称正交铺设叠层椭圆板(包括圆板和无限长板)作了数值分析。

| Abstract: | This paper studies the orthotropic elliptical plates and lami- nates with clamped edges under normal pressure producing large deflections by the singular perturbation method offered in[1,2,5], The centre deflection is chosen as a perturbation parameter,Num- erical solutions and analysis are given for orthotropic elliptical plates and symmotrically laminated cross-ply plates(including a circular plate and an infinitely long rectangular strip)made by fiber-reinforced composite materials e.g.for B-H composite materials)under various Semimajor to semiminor axes ratios. |
