| Hydrogen-assisted stress corrosion cracking simulation using the stress-modified fracture strain model
Nak-Hyun Kim, Chang-Sik Oh, Yun-Jae Kim*, Kee-Bong Yoon and Young-Wha Ma
The Journal of Mechanical Science and Technology, vol. 26, no. 8, pp.2631-2638, 2012
Abstract : "This paper proposes a numerical method to simulate hydrogen-assisted stress corrosion cracking, via coupled diffusion elastic-plastic
finite element damage analyses based on phenomenological stress-modified fracture strain model. For validation, simulated results using
the proposed method are compared with published experimental data of FeE 690T compact tension tests under air and hydrogen condition
with various constant load-line displacement rates. The simulated results agree well with experimental data."
