Switching waves in the course of elastic deformation by twisting

Abstract

Abstract Kink solutions of the Landau-Khalatnikov equation have been calculated in the case when elastic deformation by twisting is applied to a semi-infinite rod and a finite one. As a crystal without an inversion center was considered, Lifshitz invariants were taken into account in the thermodynamic potential. The specific features of kink propagation at varied boundary conditions, phase velocities and modulus of the torsion moment have been studied.
