OS1010 The Hydrogen Diffusion Analysis by Finite Element Method and Finite Difference Method
Details
Recently, many technology using hydrogen energy has been developed all over the world. Under this condition, prevention technology of Hydrogen Embrittlement is becoming an important issue. This study is aimed to try to simulate fatigue crack growth behavior of a metallic material under hydrogen environment. The simulation will be useful to predict behavior of hydrogen concentration in engineering structure. Simulation was carried out by solving the stress induced hydrogen diffusion equation. In the simulation we used a FEM-FDM coupled analysis and FEM-FEM analysis based on a multiplication method. And then, we compared the results obtained by both method.
