Эти характеристики позволяют прогнозировать развитие поверхностей исследуемых трещин вплоть до выхода на поверхность детали. Кроме того, они дают возможность уточнить оценку живучести и прочности элементов ответственного оборудования с учетом кинетики локальных процессов разрушения по контуру поверхностных разноориентированных полуэллиптических трещин с учетом локальной объемности напряженного состояния и их относительной глубины.</p></abstract><trans-abstract xml:lang="en"><p>Data of studying characteristics of linear and nonlinear fracture mechanics using numerical methods of calculation are presented. The results provide for casting of the surface crack developing up to the exit to the surface of the part. Furthermore, they provide an opportunity to specify the estimation of the survivability and durability of the elements of responsible equipment with allowance for kinetics of local processes of fracture along a contour of surface inclined semi-elliptical cracks considering local 3D character of the stress state and their relative depth.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>относительный коэффициент интенсивности деформаций</kwd><kwd>наклонные полуэллиптические малоцикловые трещины</kwd><kwd>упругие и упругопластические деформации</kwd><kwd>объемность напряженно-деформированного состояния</kwd><kwd>живучесть и прочность элементов конструкций</kwd><kwd>relative strain intensity factor</kwd><kwd>inclined semi-elliptical low-cycle cracks</kwd><kwd>elastic and elastoplastic deformation</kwd><kwd>3D character ofthe stress-strain state</kwd><kwd>durability and strength of the structural elements</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">Hayashi K., Abe H.
