在本次的研究裏,觀察薄層材料性質對承受偏軸載重之有一圓孔正交各向異性平板的應力分佈之影響。由一般化的虎克定律與一個複變方法,以及一個無尺度的分析,來研討各種薄層材料性質E1, E2, G12 與 ν12 對在承受偏軸載重之有一圓孔正交各向異性平板沿著圓孔邊緣應力分佈之影響。由這個分析的結果,可提供在結構積層複合材料平板於高精確需求的工程應用設計上之參考。再者,本次研究採用一個無尺度的分析,而此無尺度的分析是一個一般化的理論分析,所得到的圓孔邊緣應力分佈是一個一般化的理論數據分析結果,對未來各種情形的實際狀況應用可作為一個參考依據。
The effect of various offaxis angles and lamina material properties on the stress distribution of a circular cutout in an orthotropic composite plate under off-axis loading is presented. Based on the generalized Hooke’s law and the complex variable method, a dimensionless analysis is used to evaluate the influence of various elastic moduli E1, E2, G12 and ν12 on the stress distribution along the boundary of the circular cutout under various off-axis loadings. The results obtained from this dimensionless analysis provide a set of general design guidelines for structural laminates with high precision requirements in the engineering applications.
