Abstract: Transient temperature and stress distributions are analytically and experimentally investigated for a butt welded plate of HT36-steel. A two-dimensional thermal FE-model is shown to represent the ...

Abstract: A hydrogen-induced fracture process in the HAZ of a QT-steel weldment is studied numerically. Two-dimensional models are used to estimate the transient distributions of stress and hydrogen during ...

Abstract: An analytical model for diffusion of hydrogen in presence of reversible and irreversible traps in the metal is given. A numerical model for solution of the resulting system of nonlinear partial ...
