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.
