Abstract
The effect of hydrogen on dislocation-dislocation and dislocation-impurity atom interactions is studied under conditions where hydrogen is in equilibrium with local stresses and in systems where hydrogen increases the shear modulus. In the case of two edge dislocations, the effect of hydrogen is modeled by a continuous distribution of dilatation lines with strength that depends on the local hydrogen concentration. The iterative finite element analysis enabled to calculate the hydrogen distribution accounts for the stress relaxation associated with the hydrogen induced volume and the elastic moduli changes due to hydrogen. Calculation of the interactions between the dislocations accounted for all the stress field due to dislocations and hydrogen atmospheres.
