ANTI-SYMMETRICAL ANGLE-PLY LAMINATED THICK CYLINDRICAL PANELS

Hither-to-fore an unavailable analytical solution (strong form or diff erential form) to the boundary-value problem of advanced fiber reinfor ced anti-symmetric angle-ply laminated cylindrical panels of rectangul ar planform subjected to static loadings is presented. A variationally consistent higher shell theory is utilized that generates five highly coupled fourth order partial differential equations in five unknowns, three displacements, and two rotations. A boundary continuous double Fourier series-based solution functions is assumed to solve such equat ions in conjunction with the admissible boundary conditions. The numer ical results constitute the study of convergence of displacements, in- plane forces, and moments; and spatial variations of them presented in the form of contour plotting for various parametric effects. These, h ither-to unavailable solutions, and analytically obtained numerical re sults should serve as bench-marks for future comparisons of popular ap proximate methods (integral form or weak form), such as finite element , boundary element, finite difference, Galerkin approach, Rayleigh-Rit z, collocation, least-squares methods, and experimental results, etc. (C) 1998 Elsevier Science Ltd.
