- Abstract
This paper describes an approach to identify the influence of different stress type on hydrogen diffusion of the specimen which contains both tensile stress and pressure stress. The numerical method of simulating hydrogen diffusion by using software Abaqus is used to determine the influence. The simulated hydrogen diffusion is based on Fick’s second law. By comparing the concentration of different nodes which locate in different stress type area, it can be concluded that the tensile stress will drive the hydrogen diffusion but the pressure stress will hinder the hydrogen diffusion.
