The powerful mechanism of the multiscale modeling lies in the construction of a representative virtual microstructure model allowing consideration of the relevant material parameters and a virtual testing scheme bridging the equivalent quantities from microstructure to macroscopic level. In this study, we firstly aim to give an overview of various virtual microstructures with respects to the application of metals. The capability and limitation of these models to describe the comprehensive microstructure features are discussed. Secondly, we aim to give application examples incorporating such a multiscale modeling approach relying on the virtual microstructure and testing to correlate the microstructure to the yield surface for a single-phase steel, dual-phase steel, and an aluminum alloy. The focuses are on the construction of a specific virtual testing scheme for a robust prediction and upscaling of the microstructural-level data to the macroscopic phenomenological yield criteria and the texture evolution induced anisotropic hardening and r-value evolution.
