Application of Non-linear Finite Element Method to Design of Pressure Vessels by Analysis

AbstractAt present, application of non-linear finite element method to pressure vessel design still stayed in its infancy. This paper discussed engineering application and implementation notes of non-linear finite element method in pressure vessel design from five aspects as bellow: basic concept of elastic-plastic mechanics, theory basis of non-linear finite element, clauses and items of pressure vessel code, application of FEA software and practical engineering case.

Key Word: non-linear finite element, elastic-plastic stress analysis, design by analysis, pressure vessel
