The materials-by-design idea is built upon the premise that critical aspects of materials function can be captured in computational environments that includes making, measuring, and modeling materials. Past research efforts have focused on developing constitutive laws and numerical solvers but less attention has been paid to the representation of material microstructure. Results of quasi-static and high strain-rate mechanical testing indicate that mechanisms of deformation and damage nucleation are strongly dependent on material processing and resulting microstructure and are as yet a significant challenge to predict accurately. This work focuses on techniques for collection and quantification of material statistical distributions, virtual generation of materials models, and modeling requirements for simulating material response. Morphological and textural differences of forged and additively manufactured steels are discussed in the context of material response to deformation and damage, while microstructural statistics of these polycrystalline structures are discussed in the context of predictive capability development.
