The additional information to the inverse problem is components of the displacement vector measured in a set of points at the solid boundary (positional measurement). This solid performs harmonic oscillations in the first resonant frequency. The process of displacement measurement is simulated using the calculation of finite elements software ANSYS, the building of the amplitude-frequency characteristics (AFC) of the displacement, and of the selection of their values for a set of frequencies (frequency measurement). In the given numerical example, problems on the accurate identification of the elastic modulus, and material quality depending on the number of measure points and their location, as well as on the neural network architecture and the length of the training process performed by the complex-value error back propagation (CBP) algorithm are investigated.</p></abstract><trans-abstract xml:lang="ru"><p>Рассматривается применение комплекснозначных искусственных нейронных сетей (КИНС) в обратной задаче идентификации упругих и диссипативных свойств деформируемого твёрдого тела. Дополнительной информацией для решения обратной задачи являются компоненты вектора смещений, измеренные в наборе точек на границе тела (позиционное измерение), совершающего гармонические колебания в области первой резонансной частоты. Процесс измерения смещений в работе моделируется расчётом в конечноэлементном пакете ANSYS, построением амплитудно-частотных характеристик (АЧХ) смещений и выбором их значений для некоторого набора частот (частотное измерение). В приведённом численном примере исследуются вопросы точности идентификации модуля упругости и добротности материала в зависимости от числа точек измерения и их расположения, а также от архитектуры нейронной сети и длительности процесса её обучения, который осуществляется с помощью алгоритма комплекснозначного обратного распространения ошибки (КОР).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>комплекснозначные искусственные нейронные сети</kwd><kwd>идентификация механических свойств</kwd><kwd>метод конечных элементов.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>complex-valued artificial neural networks</kwd><kwd>identification of mechanical properties</kwd><kwd>finite element method.</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена при частичной финансовой поддержке РФФИ (гранты № 13-01-00196-a, 13-01-00943-a).</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The research is done with the partial financial support from RFFI (grants nos. 13-01-00196-a, 13-01-00943-a).</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">Haykin, S.
