Abstract

The dynamic response of an unsymmetric orthotropic laminated composite beam, subjected to moving loads, has been studied. The study includes the effects of transverse shear deformation, rotary and higher-order inertia. A one-dimensional element with 24 degrees of freedom, that includes extension, bending, and transverse shear deformation has been used. The response of an isotropic beam to a moving force has been compared with the available exact solution and other numerical results. Finally, the results for symmetric cross-ply and unsymmetric angle-ply laminated beams under the action of a moving load have been illustrated and compared to the results for an isotropic simple beam.
