Head Kipnis Leonid Abramovich, Registration Date 21-12-2006 Organization Uman State Pedagogical University named after P.Tychyna popup.description2 In the conditions of plane deformation by the Viner-Hopf method the calculations of initial of prefracture zone are carried out near an angular point in a homogeneous isotropic elastoplastic body, that reaches the uneven frontier of section of environments, at the end of crack which reaches the frontier of section of homogeneous isotropic elastoplastic environments, near the angular point of border of section of environments, near the end of crack that is located on verge of section of environments. The prefracture zone are designed by the straight lines of break of normal and tangent displacement, that go out from concentrators of tensions. Explored dependences of length prefracture zone and other parameters of problem. Product Description popup.authors popup.nrat_date 2020-04-02 Close
