Abstract

If a beam is subjected to impact load or distributed load locally, the height of the cross section in the beam directly under the load is deformed. In order to estimate accurately the deformation of the cross section height and the transversely normal and shear stress components, a consistent higher order deformation theory of orthotropic beams is proposed. In order to verify the validity and effectiveness of the proposed theory, the analytical solution of a simple cantilevered beam problem is obtained and compared with the existed elastic solution. It is found that the displacement and stress components are identical to the corresponding solution of the Airy stress function in elasticity theory, and the deformation of the cross section height and the transversely normal stress are also estimated reasonably.
