Transport Modeling of Hydrogen in Metals for Application to Hydrogen Assisted Cracking of Metals.

Abstract

The focus of this research was on the development of a finite element code for solute transport and trapping in linear elastic mixtures for use in modeling the hydrogen transport process in metals undergoing hydrogen assisted cracking. Specific objectives included: (1) Completion of the development of a solute transport and trapping model with coupling between the concentration, deformation, and thermal field variables and trapping at reversible and irreversible trap sites. (2) Implementation of the above theory in a finite element code. (3) Calculation of the crack tip deformations and chemical state variables for some high strength steels under a variety of loading, environment, and material conditions. (MM)
