| 摘要 | 本文研究承受中性面應力的非完全平直複 合層板在大變形情況下的屈曲及後置屈曲行為 。研究中考慮複合層板的各種參數對非線性分 析的影響。探討的參數有如:疊層數、疊層角 度、疊板厚度、長寬比、材料性質、非完全平 直的量、中性面拉力、壓力或剪力的大小、中 性面的邊界條件和垂直平面的彈性支□邊界條 件等。複合層板的理論推導上,非完全平直的 量被考量置於厚板非線性理論的應力-應變關 係式中,而所承受的負荷則被考慮置於中性面 邊界條件上;另所採用的簡單高階剪變形層板 理論因滿足表面無剪力邊界條件,故不需考量 修正係數。在分析過程中,首先使用一般性傅 利葉級數方法得到一組非線性運動方程式,然 後再利用數值方法求解。本文詳細討論各種參 數對承受中性面負荷的非完全平直複合層板之 屈曲及後置屈曲行為的影響,並以圖表詳細說 明。所得結果與文獻比較十分吻合,顯示分析結果合理恰當。 The buckling and postbuckling behaviors of initially imperfect, in-plane loading, moderately thick, laminated composite plates are investigated in this study. The effects of parameters such as aspect ratio, thickness-to- length ratio, initial imperfection, material properties, in- plane forces, and out-of-plane elastically restrained boundary conditions on buckling and postbuckling behaviors are taken into consideration. By assuming that the inplane rotation tensor is constant throughout the thickness, a simple higher order shear deformation non-linear plate theory is extended. The simple higher-order non-linear plate theory employs parabolic shear strain variation across the thickness, and requires no correction factors because it satisfies shear free surface boundary conditions. Initial imperfection is considered in the strain- displacement relations, and in-plane forces are included in the in-plane conditions. Displacement functions are expressed in the form of generalized double Fourier series. It is found that the buckling and postbuckling behaviors are significantly influenced by above parameters and results are in good agreement with published results. |
