Abstract
The work is devoted to the study of nonlinear vibrations of the lattice of the cupt7 crystal. The modeling parameters for a given crystal are considered, on the basis of which the basic properties of the material are calculated. Further, the characteristics of high-amplitude excitations are studied for various initial input values.
