摘要

The effect of nonlinearity on dynamics and the appearance of nonhomogeneous equilibrium states in a polyethylene crystal are analyzed. The role of different inputs into the nonlinearity of potentials of interaction is investigated theoretically by means of approximate equations. The solutions of these equations which describe equilibrium cracks, domain walls, bivacancies and vacancies are presented. The energies and elastic fields of these structural defects are calculated.
