456 - A thin orthotropic plate under transverse impulse loading
Cerv J., Vales F.
Abstract
The analytical solutions based on Kirchhoff, Rayleigh, Flügge and Timoshenko-Mindlin approximations of a thin elastic orthotropic plate under transverse impulse loading are discussed in the paper.The loading is supposed to be given as an arbitrary function of space and time. The results in the form of displacements and velocities are compared with those obtained by 3D finite element solution. It was found out that rapid changes in time courses of velocities and displacements are very poorly described by means of simpliest models when time dependence of the load is given by the Heaviside step function. Some calculations will be compared with experiments.
