SAFETY ASSESSMENT OF PRESSURE VESSELS

Original language description

The article deals with the study conditions breach of pressure vessels and determining the safety of using the modified criteria of Leak Before Break when a residual stress is found in the material of vessel. Superposition of residual stress, which occurs in the production of vessel by impact extrusion, with wall stress loaded internal pressure affects significantly the life and conditions of technical use. Size and character of the distribution of residual stresses were determined experimentally by hole-drilling method. This causes deformation of the surface.The numerical simulation and mathematical calculations used programs ANSYS and MATLAB. It has been shown that the results of numerical solutions are in very good agreement with the analytical solution. The main attention was focused on the application of residual stress in the numerical analysis, based on values obtained by experimental measurements hole - drilling method.
