   <abstract xml:lang="ru">
    <p>На основании данных, полученных в ходе моделирования процесса обжима и одновременного утонения элемента трубной заготовки, выполнена оценка напряженного состояния оболочек в зоне деформаций. Установлено влияние величин контактного трения, конусности инструмента и степеней деформации на максимальные значения напряжений и их неоднородность.</p>

   <trans-abstract xml:lang="en">
    <p>Based on the data obtained during the simulation of breaking-down and thinning-out simultaneously of the pipe stock element, the stress state of pipe jackets in the deformation zone has been evaluated. The influence of the contact friction magnitude, the  tool conicity and the degrees of deformation on the maximum stress values and their heterogeneity have been determined.</p>
