Buckling analysis of laminated cylindrical composite shell panel under mechanical and hygrothermal loads
Keywords:buckling, composite shell panels, hygrothermal effects, finite element, first-order shear deformation theory
This paper deals with buckling of analysis multilaminated cylindrical shell panels subjected to axial and hygrothermal loadings. The geometrical non-linear analysis is carried out using the Finite Element Method based on a single layer first shear deformation theory. A nine-nodal isoparametric element with 5 degrees of freedom per node is considered. The effects of different number of layers, lamination angles, length to width ratios and hygrothermal effects are studied.
