pages 67 - +10p., full text

The numerical dispersion of two-dimensional finite elements was studied. The outcome of this dispersion study was verified by the numerical and analytical solutions to the longitudinal impact of two cylindrical bars. In accordance with the results of the dispersion analysis it was proved that the quadratic elements showed better accuracy than the linear ones.
