Evolution of the effective chemical potential \({{\overline{\mu }}}\)versus loading timetfor different microstructures and mobility parameters of the individual phases. RVEnn denote equal-sized RVEs with lateral length of n mm made up of \(n \times n\) unit cells. nRVE11 denotes scaled RVEs made up of one unit cell having a lateral length of n mm. In the plots, the mobility parameters of the matrix and the inclusion are given by (units in \(\text {mm}^4/(\text {Ns})\)) \(M_{mat} = 10^{-1}\) and \(M_{incl}=10^{-4}\) (a and d), \(M_{mat} = 10^{-1}\) and \(M_{incl}=10^{-2}\) (b and e) and \(M_{mat} = 5.0\) and \(M_{incl} = 10^{-4}\) (c and f), respectively. We observe that the transient response of the individual RVEs is sensitive with respect to changes of material parameters, but converges to a unique stationary solution
