Although some integration between different computational material tools have been shown already in this case study about the A356 Al alloy control arm, the most important integration is into the macroscale constitutive model. As discussed in Chapter 2, the ISV theory is an excellent repository to receive lower length information. ISV theory also was developed as a continuum formulation and as such can be incorporated into finite element codes. It is essentially the bridge from microstructural information to stress and failure analysis in the context of a hierarchical multiscale modeling methodology. Figure 7.60 shows the connections between the different length scales and the macroscale ISV continuum model.
Before we proceed with the macroscale model discussion, it is worth reminding ourselves of the connections with the lower length scales that were of interest in this case study:
