Figure 7: Simulated fields for the RVE of soft/hard composite “Cu/40CrNiMo/Cu” with columnar and equiaxial microstructures at t =144 s. vM ε 〈 〉 is depicted in Fig. 8. First of all, the difference in field trends and values between the soft Cu and hard 40CrNiMo phases is evident for all RVEs. For example, compared to the 40CrNiMo phases, the vM σ 〈 〉 and a c τ 〈 〉 plots for Cu-phase demonstrate no elastic response and initiate directly from plastic deformations with a slow hardening regime at higher vM ε 〈 〉 . On the other hand, deformation of 40CrNiMo In more detail, the evolution of different fields with
