The dynamic contact of a spherical indenter and an orthotropic plate is investigated. The plate possesses curvilinear anisotropy and undergoes pre-stressing longitudinal force together with two moments. The dynamic behaviour of the target is described by wave equations which take into account the transverse shear and rotary inertia of the cross sections and allow for modelling the process of propagation of elastic waves after the impact. The asymptotic method of the series expansion of unknown quantities in terms of Legendre polynomial and Laurent seriesin the vicinity of the sought point is used as a method of solution. The dynamic characteristics of the interaction are determined and the influence of the preloaded target on these dynamic characteristic is investigated.
