The object of research is the processes of geometrically nonlinear elastic-plastic deformation of spatial bodies of complex shape and structure under the influence of dynamic loading. Subject of research - parameters of nonlinear deformation, plastic deformations, stress waves, displacement, velocity and acceleration, contact conditions. The aim of the work is to develop theoretical bases and new methods of research and analysis of processes of geometrically nonlinear elastic-plastic deformation of massive and thin-walled 3D bodies under the action of dynamic loading taking into account contact interaction and essential values of linear and nonlinear deformations.  Product Description popup.authors Bazhenov Viktor A Vabishchevych Maksym O Karnauhov Vasyl H Lukianchenko Olga O Maksimyuk Yurii V Pyskunov Serhii O popup.nrat_date 2021-02-20 Close
