Southern Regional Center for Lightweight Innovative Design (SRCLID)

SRCLID plans to reduce emissions and posture the US to have less reliance on foreign oil, focusing our research and educational enterprise on lightweighting vehicles.

Vision: We develop multiscale physics-based material models for lightweight alloys, steel alloys, and polymers that are experimentally validated to be used in engineering practice for design optimization of components, systems, and materials for the southern automotive corridor of the US.

Mission: We provide a design methodology that includes physics-based material models that include uncertainty in consideration of the material history. This entails theory development, experimental characterization, and large scale computing. The development of new materials and math-based tools is sought for use in next-generation vehicles under various crash and high-speed impact environments.

Goals: The goals are threefold: (1) an experimentally validated cradle-to-grave modeling and simulation effort to optimize automotive and truck components for various materials (aluminum, steel, and magnesium alloys, and polymer-based composites) with consideration of uncertainty in order to decrease weight and cost, and yet increase the performance and safety in impact scenarios; (2) the multiscale (“From Atoms to Autos”) modeling philosophy in which we quantify the microstructure-property relations by evaluating various length scales, starting at the atomic level for each step of the manufacturing process for vehicles; and (3) an integrated K-PhD educational program to educate students on lightweight designs and impact scenarios.
