摘要：

Propagation of longitudinal solitary waves in rods made of an isotropic material was studied by computer simulations. The analysis of the problem was based on the equation derived by Porubov from Mumaghan's free energy model. Amplitudes, velocities and shapes of pulses of propagating solitary waves were determined both for auxetic materials, i.e. exhibiting negative Poisson's ratio, and for common ones - of positive or zero Poisson's ratio.
