| Abstract: | A typical chemical equipment model was founded using Shell unit because the Shell unit in ANSYS software could not obtain the stress linearization data. Through the concrete analysis of the data of Shell 51 unit, the calculation method and corresponding formula of the evaluation data of stress linearization was given, the analysis calculation of stress linearization of Shell 51 unit model was realized. Some important conclusions were derived with practical examples. |
