Modeling hydrogen transport and hydrogen-induced embrittlement

Abstract

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.
