     in this paper the nonlinear dynamic analysis of an isotropic rectangular plate under influence of an accelerated/decelerated moving force is studied. the governing nonlinear coupled partial differential equations of motion are derived using hamilton’s principle based on the large deflection theory. then the galerkin’s method is applied to transform the equations of motion into the three coupled ordinary differential equations and then numerically integrated to compute the dynamic responses. the appropriate parametric study by taking into account the effects of the magnitude of the traveling and the velocity of the traveling force with a constant acceleration/deceleration is carried out. it was seen that the existence of nonlinear terms in the governing coupled pdes of motion renders stiffening behavior on the dynamic responses of the plate when traversed by a moving force.
