The present paper provides a hierarchical message passing approach to multi-scale modeling of elevated temperature deformation using a series of computational techniques. Deformation is modeled by considering the contributions of diffusional creep, grain boundary sliding, and dislocation creep. Molecular Dynamics is used to understand the effect of grain misorientation and grain boundary chemistry on sliding behavior. A microstructure based model which accounts for the individual creep mechanisms is used to determine the relationships between strain rate, strain, and stress. Finally, a finite element model using the predicted constitutive material behavior is used to determine strain evolution in a formed component. This method has been used to predict the effect of microstructural variations on forming of actual vehicle components. It provides the framework for linking different computational techniques through selective informing of higher length scales by the output from lower length scales. Examples of calculations for AA5083 and AZ31 alloys on biaxial bulges and an automotive component will be provided.
