This paper concerns the finite difference solution to the elastic field in a cantilever beam of unidirectional orthotropic composite material. The mixed boundary value plane elastic problem is formulated in terms of a single displacement potential function. The numerical scheme developed is demonstrated for a particular case of a boron/epoxy cantilever beam for two different loading conditions. Numerical results of different stress and displacement components at different sections of the beam are presented in the form of graphs. With a view to verifying the finite difference results, solutions are also obtained by finite element method. The comparison of the results ensures that the present displacement potential based finite difference scheme is relatively simple, reliable, and accurate enough to analyze the elastic field in orthotropic composite structures under mixed boundary conditions. |
