В качестве поверхности нагружения принимается обобщеннаяфункция текучести Мизеса, соответствующая многочисленным экспериментальным дан-ным. Показано, что обобщенная модель Мизеса является удобной для анализа процессовпространственной деформации с помощью специального изображающего параметрическо-го пространства. Численная реализация метода иллюстрируется на примере пластическо-го сжатия материала в условиях трехмерной деформации. Показано, что распределениенапряжений и скоростей течения зависит от текущего соотношения размеров слоя приосаживании.</p></abstract><trans-abstract xml:lang="en"><p>The method of analysis of spatial fields of stresses and velocities in pro-cesses of plastic flowis given, based on mapping of flow zones in deviator space of stresses. A generalized Mises flowfunction corresponding to numer-ous experimental data is taken as the loading surface. It isshown that the generalized Mises model is convenient for analysis of spatial deformation processeswith the power of a special depicting parametric space. The numer-ical implementationof the method is illustrated by the example of plastic compression of a material under threedimensionaldeformation conditions. It is shown that the distribution of stresses and flow ratesdepends on the current ratio of layer sizes during settling.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ильюшин A.
