To this purposes the heating of nanocluster was carried out by stochastic forces method. The calculation of number of characteristics was made in certain time steps number. In particularly it were computed the linear sizes of nanostructeure under investigation, its volume, the system temperature. Further the magnitudes of TLC were obtained by known expressions with the help of interpolation; the TLC dependences on nanostructure size were plotted. It was shown that the TLC depends on both nanostructure size and nanostructure shape.</p></abstract><trans-abstract xml:lang="ru"><p>В работе проведено молекулярно-динамическое исследование коэффициента теплового расширения (ктр) нанокластеров меди сферической и кубической формы в широком диапазоне размеров. Для этого был проведен нагрев нанокластера методом стохастических сил. При этом через определенное число шагов по времени проводился расчет ряда характеристик, в том числе найдены линейные размеры исследуемой наноструктуры, ее объем и температура. Далее были найдены значения ктр, построены его зависимости от размера и формы наностуктуры. Показано, что коэффициент теплового расширения зависит от размера наноструктуры и с увеличением размера приближается к экспериментальному значению для макрообразцов.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>молекулярно-динамическое моделирование</kwd><kwd>медный нанокластер</kwd><kwd>коэффициент теплового расширения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Molecular dynamic modeling</kwd><kwd>copper nanocluster</kwd><kwd>thermal expansion coefficient</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке интеграционного проекта ОЭММПУ РАН № 13 «Трибологические и прочностные свойства структурированных материалов и поверхностных слоев».</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sekkal W., Bouhafs B., Aourag H., Certier M.
