Postbuckling behaviour of curved panels of generally layered composite materials

摘要: Abstract An analysis for the postbuckling behaviour of compressively loaded, cylindrically curved panels generally layered anisotropic composite materials is presented. The 36 coefficients in constitutive relations are all taken into account. A pair coupled non-linear differential equations solved conjunction with simply supported boundary conditions. Both double sine series and sine-squared used deflection function, while characteristic beam function to express stress function. Numerical computations performed a number different lay-ups, curvatures materials. Comparison between present work available theoretical experimental data carried out special case flat plate.
