Sammendrag
This document provides the theory manual and user manual for two finite elements for the modeling of hydrogen-induced embrittlement of metallic materials. The cohesive zone element (CZE) allows to simulate the creation of new surfaces and the corresponding absorption of energy. The absorption of energy is made a function of the hydrogen concentration. The volume element (DIFEL) accounts for mechanical deformation, the transport of hydrogen, and the kinetics of trapping and detrapping.

Hydrogen informed Gurson model for hydrogen embrittlement simulation
Yu, Haiyang; Olsen, Jim Stian; Alvaro, Antonio; qiao, lijie; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2019)Hydrogen-microvoid interactions were studied via unit cell analyses with different hydrogen concentrations. The absolute failure strain decreases with hydrogen concentration, but the failure loci were found to follow the ...
