We considered a model crystal with A3B stoichiometry. The investigation was carried out using atomistic modeling through molecular dynamics. The interatomic interaction was determined by a potential obtained through the embedded atom method, which approximates the properties of the Pt3Al crystal. The effect of NST is an important property of many discrete structures. Its existence requires the discreteness and nonlinearity of the medium, as well as the presence of a forbidden zone in its spectrum. This work focuses on the differences in the NST effect due to the anisotropy of crystallographic directions. Three planes along which the disturbance caused by NST propagated were considered: (100), (110), and (111). It was found that the intensity of the disturbance along the (100) plane is an order of magnitude lower than for more densely packed directions. Differences in the shape of solitary waves depending on the propagation direction were shown. Moreover, all waves can be described by a single equation, being a solution of the discrete variational equations of macroscopic and microscopic displacements, with different parameters, emphasizing the unified nature of the waves and the contribution of crystal anisotropy to their properties. Studying the NST phenomenon is essential due to numerous applications of the latter, such as implications in information transmission and signal processing. Understanding how disturbances propagate in discrete media could lead to advancements in communication technologies, data storage, and signal amplification where the earlier mentioned ability to describe it with analytical equations is of particular importance.<\/jats:p>","DOI":"10.3390\/computation11100193","type":"journal-article","created":{"date-parts":[[2023,10,2]],"date-time":"2023-10-02T11:56:49Z","timestamp":1696247809000},"page":"193","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["The Influence of Crystal Anisotropy on the Characteristics of Solitary Waves in the Nonlinear Supratransmission Effect: Molecular Dynamic Modeling"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6410-1594","authenticated-orcid":false,"given":"Pavel V.","family":"Zakharov","sequence":"first","affiliation":[{"name":"Department of Physics, Peter the Great St. Petersburg Polytechnic University, 29, Polytechnicheskaya Str., St. Petersburg 195251, Russia"},{"name":"Institute for Metals Superplasticity Problems, Ufa 450001, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5975-4849","authenticated-orcid":false,"given":"Elena A.","family":"Korznikova","sequence":"additional","affiliation":[{"name":"The World-Class Advanced Digital Technologies Research Center, Peter the Great St. Petersburg Polytechnic University, 29, Polytechnicheskaya Str., St. Petersburg 195251, Russia"},{"name":"Technological Machines and Equipment Department, Ufa State Petroleum Technological University, Ufa 450064, Russia"}]},{"given":"Artem A.","family":"Izosimov","sequence":"additional","affiliation":[{"name":"Department of Surgical Dentistry, Bashkir State Medical University, Ufa 450008, Russia"}]},{"given":"Andrey S.","family":"Kochkin","sequence":"additional","affiliation":[{"name":"Department of Physics, Altai State University, Barnaul 656049, Russia"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"134102","DOI":"10.1103\/PhysRevLett.89.134102","article-title":"Energy transmission in the forbidden band gap of a nonlinear chain","volume":"89","author":"Geniet","year":"2002","journal-title":"Phys.
