Установлено, что сечение максимума контактных нормальных напряжений всегда находится в зоне отставания и существенно "отстает" от нейтрального сечения. Приведены количественные данные о влиянии технологических параметров процесса холодной прокатки без натяжения на положение максимума эпюр контактных нормальных напряжений относительно нейтрального сечения и дан их анализ.</p></abstract><trans-abstract xml:lang="en"><p>Ascertained data as to the character of the contact stresses distribution have been obtained thanks to the application of the ascertained solution for the differential equation of longitudinal forces’ balance by the cold rolling. The mentioned solution takes into account the kinematics particularities of a deformation zone. These data have been used to determine the position of the maximum in contact of normal stresses relative to the neutral plane. It has been established that the section of the maximum in contact normal stresses is always situated in the backward slip zone and is substantially behind the neutral plane. This fact corroborates conclusions about the discrepancy of these two sections made earlier by A. Nadai, A.A. Korolyov and A.I. Tselikov. It represents the answer to one of the least studied questions in the up-to-date theory of the thin-sheet (cold) rolling. The qualitative data about the influence of technological parameters of the cold rolling process without tension upon the situation of the maximum for epures of the contact normal stresses relative to the neutral plane have been presented in the paper as well as their analytical treatment.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>холодная прокатка</kwd><kwd>дифференциальное уравнение</kwd><kwd>контактные напряжения</kwd><kwd>нейтральное сечение</kwd><kwd>сечения максимума нормальных напряжений</kwd><kwd>несоответствие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cold rolling</kwd><kwd>differential equations</kwd><kwd>contact stresses</kwd><kwd>neutral plane</kwd><kwd>the position of the maximum in contact normal stresses</kwd><kwd>discrepancy</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">Целиков А.И.
