Forced vibration of unsymmetric laminated composite beams under the action of moving loads

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.
