Three-Dimensional Elastodynamics Of Thick Plate Strip Subjected To Moving Line Loads

The fundamental solution for a line load moving uniformly on an infinite, homogeneous, isotropic thick plate strip is presented and discussed. The problem solution is derived by using Fourier transformation with respect to a moving reference frame in conjunction with Helmholtz potentials that obtains the response of the system by applying the displacement and stress conditions at boundary surfaces. The effects of load velocity and plate thickness on the basic dynamic field quantities such as the mid-plane displacement and bending moment amplitude along the z-axis are also evaluated and discussed.
