  Anisotropy of friction force is proved to be an important factor in various
contact problems. We study dynamical behavior of thin plates with respect to
symmetric and asymmetric orthotropic friction. Terminal motion of plates with
circular and elliptic contact areas is mainly analyzed. Evaluation of friction
forces for both symmetric and asymmetric orthotropic cases are shown. Regular
pressure distribution is considered. Differential equations are formulated and
solved numerically for a number of initial conditions. Examples show
significant influence of friction force asymmetry on the motion.
