本研究主要在於探討承受壓力之纖維強化塑膠基層板之潛變挫曲及潛變大撓度變形。考慮材料非線性及幾何缺陷對於結構黏彈反應之影響。複合材料非線性黏彈應變-應力關係是採用Schapery單迴旋積分式來描述。文中詳細探討對稱正交積層板承受軸向壓力所衍生之結構潛變行為。使用的板理論為古典積層板理論，並引入von Karman撓性板假設。利用虛功原理求取約略解。為簡化分析程序及節省數值計算時間，本研究採用準彈性分析。 The objective of this research is to investigate the creep buckling and large creep deflection of fiber-reinforced-plastic (FRP) laminated plates under compression. The effects of material nonlinearity and geometrical imperfection on the viscoelastic behaviors are examined. The nonlinear viscoelastic strain-stress relation is described by Schapery's single- convolution- integral constitutive law. The creep responses of symmetric cross-ply laminates subjected to the in-plane axial compression are thorough investigated and reported in this study. The analysis is based on the classicallaminate theory in conjunction with the von Karman flexible plate hypothesis. The approximate solutions are obtained using the principle of virtual work. In order to simplify the analysis procedure and improve the numerical computation efficiency, the quasi-elastic approach is adopted in this study.
