Parametric investigations on dynamics of cracked thin rectangular plates, excited by a moving mass

Dynamic analysis of cracked thin rectangular plates subjected to a moving mass first is investigated in this paper. To end, the eigenfunction expansion method utilized solve governing equation. For time, intact plate orthogonal polynomials combination with admissible crack functions as composition, are employed formulation, required professional computer programming The proposed approach guarantees upper bound true solution, which property an appropriate numerical solution. Parametric investigation performed determine effect weight, velocity, length, and angular orientation well plate’s aspect ratio, on dynamic response plates. results confirm, that has greater impact than load responses Furthermore, there nonlinear relation among enhancing various boundary conditions, magnifying weights, elevating velocities, lengthening raising inclined angels augmenting ratios.
