Presented by Will Joost, Vehicle Technologies Office, U.S. Department of Energy. Improved performance and manufacturability of lightweight structural materials is critical for many industries. In the automotive sector, reducing the weight of a vehicle, or “lightweighting”, is frequently cited as an approach that can support automakers in achieving improved fuel economy. However, many barriers exist to the implementation of lightweight structural materials such as aluminum alloys, magnesium alloys, advanced steels, and carbon fiber composites - improvements in material performance, manufacturability, and cost are all necessary for wider adoption. In 2011 the President announced the Materials Genome Initiative (MGI) which seeks to discover, develop, manufacture, and deploy advanced materials at least twice as fast as possible today, at a fraction of the cost through a combination of experimental tools, computational tools, and digital data. The methods, infrastructure, and philosophy supported by MGI provide unique opportunities for efficiently and rapidly addressing technical challenges in lightweight materials. A brief analysis of lightweighting energy impacts will be combined with a discussion of the technical challenges in several material systems. The growing field of Integrated Computational Materials Engineering (ICME) will be introduced and opportunities for applying ICME will be discussed using automotive material examples. ICME will be contrasted against other applications of modeling and simulation with a focus on identifying the elements of an ICME approach which are most beneficial to accelerated materials development. Examples of ongoing work in this area will be provided along with a discussion on future opportunities and pitfalls.
