A multi-scale, computational design approach for aluminum sheet alloys, which includes key inputs from the electronic, atomistic, microstructural, and continuum length scales, is re- viewed within the context of room and elevated temperature forming. Specific examples, which are aimed at improv- ing aluminum sheet materials for au- tomobile components, include predic- tion of flow curves from tensile testing, forming limit diagrams, and compo- nent forming.
