Numerical simulation of the transient hydrogen trapping process using an analytical approximation of the McNabb and Foster equation. Part 2: Domain of validity

Modeling hydrogen dragging by mobile dislocations in finite element simulations

“…The main features of this configuration are first recalled, and the TTD implantation is then compared to bibliographic results for 𝐷 " = 0 mm 2 /s (no dragging). It is worth noting that the results presented in [18] have been obtained by using a complete different implementation scheme, based especially on an approximation of the solution of the McNabb and Foster equation (see [43,58] for more details).…”

“…In Figure 8 are plotted the comparison between the normalized 𝐶 ! repartition at the end of the mechanical loading for 𝜏 =1.3 s for different trapping kinetic, and computed using the scheme proposed by Benannoune et al [43,58] on the one hand, and with the current implementation strategy on the second hand. The two approaches give the same results, and are consequently equivalent for 𝐷 " = 0 mm 2 /s.…”
