Investigation of elastic field of a short orthotropic composite column by using finite-difference technique

Abstract

The elastic field of a short column of orthotropic composite material under a linearly varying distributed load is analysed using displacement potential formulation. The finite-difference technique is used to obtain the numerical solutions of different parameters of the elastic field. The differential equations associated with the boundary conditions and the governing equation are approximated by their corresponding finite-difference forms, which are then applied, respectively, to the boundaries and the interior nodal points of the discretized column. To demonstrate the elastic behaviour of the fibre reinforced composite column, the results of displacements and stresses at different sections are presented in a graphical form.
