Примером такого поведения материала являются гидродинамические течения, для которых возможна аналогия с ротационно-трансляционными вихрями.</p></abstract><trans-abstract xml:lang="en"><p>According to modern concepts of physical mesomechanics, the elementary act of plasticity is a translational-rotational vortex, which ensures convective flow of the material under large plastic deformations.
