Creep and Swelling Deformation in Structural Materials During Fast-Neutron Irradiation

A critical test of the classical rate theory for void swelling

“…The last two sets are found to depend strongly on the loop and the void radius, respectively. The bias factors for dislocations, on the other hand, must be averaged over different configurations, taking into account edge and screw characters and the mutual cancellation of the long-range stress fields when dislocations form multipole configurations [10] or walls. For all these reasons, the net bias evolves with the microstructure.…”

“…which is exactly the same as the expression in Equation (30). The fact that there are two relaxation times Involved in the slit tube relaxation is just due to the fact that it is in plane strain.…”

Irradiation creep relaxation of void swelling-driven stresses

“…(1) and (2) reduce to the conventional ''B o þ D _ S'' deviatoric creep and stress-affected swelling equations developed by Wolfer and coworkers [5][6][7]. Eq.…”

“…Using Eqs. (1)- (6), one can show that the total elastic plus inelastic axial strain rate, which is the sum of…”

“…In that paper further comparisons are provided to the conventional ''B o þ D _ S'' irradiation creep equation that was developed in a series of papers by Wolfer and co-workers [5][6][7]. This equation has been used extensively in analysis and reporting of irradiation creep and stress-affected swelling data [8].…”
