Finite element analysis of multi-span functionally graded beams under a moving harmonic load

A finite element procedure for vibration analysis of multi-span functionally graded material (FGM) beams subjected to a moving harmonic load is presented. The material properties of the beam are assumed to vary continuously in the thickness direction by a power-law distribution. The finite element f...
