Static bending analysis of laminated cylindrical panels with various boundary conditions using the differential cubature method

S. Mahmoud Mousavi and Mohamad M. Aghdam

Vol. 4 (2009), No. 3, 509–521
Abstract

This paper deals with the application of the differential cubature method (DCM) to the bending analysis of laminated cylindrical panels. Symmetric and unsymmetric laminate, with various combinations of clamped, simply supported and free boundary conditions, are considered, with either uniform or sinusoidal transversely distributed loads. Using first-order shear deformation theory, fifteen first-order partial differential equations are obtained, containing as many unknowns in terms of displacements, rotations, moments, and forces. Comparison of the results obtained by DCM shows very good agreement with those of other numerical and analytical methods, with decreased computational effort. Further, in this method, a free boundary condition and unsymmetric laminates do not violate the accuracy of the results.
