Simulation of Strain Strengthening for Cryogenic Pressure Vessels Utilizing ANSYS Workbench
To fully examine the safety of strain strengthened vessels in the manufacturing process and in-service conditions,ANSYS Workbench software is used to conduct a nonlinear finite element simulation of the strain strengthening for the sample tank of the cryogenic pressure vessel,and the analysis of the strain and deformation is carried out during the strengthening process,including pressurization,pressure holding and depressurization.The results show that the simulation analysis provides a reference for the improvement of the utilization of austenitic stainless steel and the weight lighting of cryogenic pressure vessels.
