摘要：
A finite element (FE) model is presented in this work that simulates and predicts the mechano-chemical corrosion behavior of welded joint under different plastic strains. The FE model contains two parts: the stress calculating of welded joint using Abaqus software and the chemical reaction of welded joint using COMSOL Multiphysics((R)) software. The simulating corrosion depth of weld metals center are close to experimental measurements on the welded joint under different plastic strains. Meanwhile, effect of weld reinforcement, strain, and welding material on the mechano-chemical corrosion behavior of welded joint under different plastic strains was investigated using the FE model.
