摘要
采用Ｗｈｉｔｃｏｍｂ薄膜分层屈曲模型，根据Ｒａｙｌｅｉｇｈ－Ｒｉｔｚ法建立了考虑温度效应时复合材料层合板分层屈曲的稳定性特征方程。计算得出了均匀温度场中对称铺设层合板椭圆形分层屈曲的临界压缩载荷及屈曲临界温升。
Based on Whitcomb delamination buckling model,a Rayleigh Ritz analysis is presented to determine the load or the temperature at which delamination buckling will occur for a composite laminate with a single elliptical delamination.The effect of temperature on buckling load and temperature dependent elastic and thermal properties are considered.The critical load and critical temperature values of delamination buckling are investigated for delamination with different sublamination angle and ratio of major and minor axis of symmetrical angle ply laminate.
