Построены решения краевых задач механики, в которых определяющие дифференциальные уравнения имеют дробный порядок. Рассмотрены, в частности, такие задачи, как модель «фрактального» осциллятора, модельная задача о распространении динамических волн в массивах горных пород, модельные задачи о распространении волн деформаций в деформируемых вязкоупругих средах (полубесконечном вязкоупругом стержне) для различных моделей вязкоупругости. При построении решений использовался алгоритм Майнарди и преобразование Лапласа. Найдены модельные решения для рассмотренных классов задач. Получены асимптотические решения уравнений распространения волн в вязкоупругих средах при различных моделях вязкоупругости.</p></abstract><trans-abstract xml:lang="en"><p>In this paper, we represent new examples of constructing model problems of the mechanics of a deformable solid using a fractional differentiation apparatus. The solutions to boundary problems of mechanics are found, in which the defining differential equations have a fractional order. In particular, such problems as a model of a “fractal” oscillator, a model problem on the dynamic of wave propagation in rock, model problems on the deformation of wave propagation in deformable viscoelastic media (a semi-infinite viscoelastic rod) for various viscoelasticity models are considered. When building the solutions, the Mainardi algorithm and the Laplace transformation are used. Model solutions for the considered problems are built. Asymptotic solutions of wave propagation equations in viscoelastic media under different viscoelasticity models are obtained.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дробная производная Римана – Лиувилля</kwd><kwd>дробная производная Капуто</kwd><kwd>преобразование Лапласа</kwd><kwd>алгоритм Майнарди</kwd><kwd>модель «фрактального» осциллятора</kwd><kwd>волновое фрактальное уравнение геомеханики</kwd><kwd>дробные модели вязкоупругости</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fractional derivative of Riemann – Liouville</kwd><kwd>fractional Caputo derivative</kwd><kwd>Laplace transform</kwd><kwd>Mainardi algorithm</kwd><kwd>fractal oscillator model</kwd><kwd>wave fractal equation of geomechanics</kwd><kwd>fractional viscoelasticity models</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Самко, С.
