Abstract

The static behaviour of laminated
composite and sandwich beams subjected to various sets of boundary conditions
is investigated by using the Timoshenko beam theory and the Symmetric Smoothed
Particle Hydrodynamics (SSPH) method. In order to solve the problem, a SSPH
code which consists of up to sixth order derivative terms in Taylor series
expansion is developed. The validation and convergence studies are performed by
solving symmetric and anti-symmetric cross-ply composite beam problems with
various boundary conditions and aspect ratios. The results in terms of mid-span
deflections, axial and shear stresses are compared with those from previous
studies to validate the accuracy of the present method. The effects of fiber
angle, lay-up and aspect ratio on mid-span displacements and stresses are
studied. At the same time, the problems not only for the convergence analysis
but also for the extensive analysis are also solved by using the
Euler-Bernoulli beam theory for comparison purposes.
