The method permits to obtain the problem solution effective for the full range of the problem characteristic geometrical and physical parameter values. Some cases when Young’s moduli of the layer and the substrate differ more than a hundredfold are analyzed. The obtained contact stresses for different values of the foundation stiffness are compared with the formerly known results for the nondeformable foundation case. It is shown that when the elastic properties of the layer and the substrate differ a hundredfold, maximum difference between these results is less than 3%. The relationship between the pressing force and the radius of the sphere is determined. The question is put owing to the control problem of the thin coatings elastic properties.</p></abstract><trans-abstract xml:lang="ru"><p>Приводится эффективный метод построения приближённого аналитического решения контактной задачи о внедрении сферического индентора в мягкий упругий слой , лежащий на жёстком упругом основании. Метод позволяет получить решение задачи, эффективное для всего диапазона значений характерных геометрическ их и физических параметров задачи. Рассмотрены случаи отличия модулей Юнга слоя и подложки более, чем в 100 раз. Полученные контактные напряжения для различной степени жёсткости основания сравниваются с ранее известными результатами для случая недеформируемого основания; показано, что при отличии свойств слоя и подложки в 100 раз , максимальная разница между результатами составляет менее 3 % . Определена связь между вдавливающей силой и радиусом сферы . Задача поставлена в связи с проблемой контроля упругих свойств тонких упругих покрытий.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>контактная задача</kwd><kwd>сферический индентор</kwd><kwd>эффективное решение</kwd><kwd>мягкий упругий слой</kwd><kwd>упругое основание</kwd><kwd>модуль Юнга</kwd><kwd>контроль упругих свойств .</kwd></kwd-group><kwd-group xml:lang="en"><kwd>contact problem</kwd><kwd>spherical indenter</kwd><kwd>effective solution</kwd><kwd>soft elastic layer</kwd><kwd>elastic foundation</kwd><kwd>Young’s modulus</kwd><kwd>control of elastic properties.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при частичной поддержке РФФИ (11-08-91168-ГФЕН_а, 12-07-00639_а) и Министерства образования и науки РФ (ГК № 11.519.11.3028, соглашения № 14.B37.21.1131,</funding-statement><funding-statement xml:lang="en">The research is done with the partial financial support from RFFI (11-08-91168-GFEN_a, 12-07-00639_a) and from The Ministry of Education and Science of the Russian Federation (State Contract No. 11.519.11.3028, Agreements Nos. 14.B37.21.1131, 14.132.21.1693).</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">Tsui, Y.
