Abstract

This paper analysis dynamic response of porous functionally graded material (p-FGM) multi-span sandwich beams subject to two moving loads. The core of sandwich beam is fully ceramic and skins are composed of a porous functionally graded material. The vibration differential equations of beams are established based on the finite element method (FEM). Using the Newmark direct integration method, the dynamic response of the beam is calculated. A detailed study is performed to investigate the influences of material, moving load speed, porous parameter and distance between two moving loads on the dynamic response of p-FGM multi-span sandwich beams.
