description: The topic of the final qualifying work: Â«The study of upper shelf energy during testing pipe steels with a DWTTÂ». The work is devoted to the development of recommendations on thick sheet manufacturing technologies in order to reduce rejection based on the results of DWTT, as well as the study of plasticity and destruction of pipe steel samples during DWTT. The relevance of the work is due to the requirements for increasing the impact properties of a thick sheet of pipe steels due to the possible elimination of the causes of a decrease shear area at DWTT. To achieve these goals, it is necessary to solve the following tasks: 1. Familiarization with modern methods of finite element (FE) modeling. 2. Development of a FE-model of deformation and destruction of samples by falling cargo. 3. Performing tests on the Gleeble to determine the rheological properties of deformable steel. 4. Performing calculations, debugging and calibration of the model. 5. Reproduction of the technique of transition from the final deformed state of the samples to the visual characteristic of destruction - the shear area of the samples. The practical significance of the work consists in finding possible reasons for the decrease a shear area of samples after DWTT with satisfactory mechanical properties and impact strength.
