Abstract

This paper presents the finite element algorithm and results on dynamic response of cracked plate structure an elastic foundation subjected to moving oscillator with a constant velocity and any motion orbit. The response to a single moving oscillator is first investigated and then the effects of crack, velocity, elastic foundation stiffness, and stiffness of the spring of moving oscillator are studied. Results indicate that the number of crack and the foundation stiffness and the velocity of the oscillator moving have significant effects on the dynamic response of the cracked plates.
