Orynyak, Доктор технічних наук Registration Date 05-12-2025 Organization National Technical University of Ukraine «Igor Sikorsky Kyiv Polytechnic Institute» popup.description1 The purpose of the work is to improve and algorithmize the calculation method of matched sections for solving plane problems of the theory of elasticity and for calculating plates. These two parts form the basis for further improvement of the method for more complex models and geometric configurations. The next step should be to develop a method for closed shells - these are cylindrical, conical and toroidal, bordering a continuous pipeline (beam element), which is considered as having 12 degrees of freedom. The uniqueness of the development is precisely that the system of shell elements, into which the pipe section is divided along the circumference, and each of which also contains 12 degrees of freedom, can be matched with one beam element. popup.nrat_date 2025-12-05 Close
