Integrated Computational Materials Design: From Genome to FlightWhen:May 3, 2012
Where:CAVS Seminar Room 2200
Greg Olson will be speaking at a seminar titled "Integrated Computational Materials Design: From Genome to Flight" at the Center for Advanced Vehicular Systems. The seminar will be held on May 3, 2012 at 3pm in the CAVS seminar room 2200.
The numerical implementation of established materials science principles in the form of purposeful engineering tools has brought a new level of integration of the science and engineering of materials. Building on a system of fundamental databases now known as the Materials Genome, parametric materials design has integrated materials science, applied mechanics and quantum physics within a systems engineering framework to create a first generation of designer "cyberalloys" that have now entered successful commercial applications, and a new enterprise of commercial materials design services has steadily grown over the past decade. The successful demonstration of the broad applicability of a thermodynamics-based genomic design approach across metals, ceramics, polymers and composites in the 1990s established a basis for the DARPA-AIM initiative of the 2000s which broadened computational materials engineering to address acceleration of the full materials development and qualification cycle. A new level of science-based AIM modeling accuracy has now been achieved under the ONR/DARPA "D3D" Digital Structure consortium using a suite of advanced 3D tomographic characterization tools to calibrate and validate a set of high fidelity explicit 3D microstructural simulation tools spanning the hierarchy of microstructural scales. A surface thermodynamic genome database predicted directly from validated DFT quantum mechanical calculations employing the highly accurate FLAPW method have generated novel “Quantum Steels” completely eliminating intergranular stress corrosion cracking at the highest strength levels. Integration with the full suite of fundamental databases and models has recently demonstrated the historic milestone of accelerated flight qualification for aircraft landing gear through application of the fully integrated computational design + AIM methodology.
Greg Olson is Walter P. Murphy Professor of Materials Science and Engineering at the McCormick School of Engineering and Applied Science at Northwestern University. He directs the Materials Technology Laboratory/Steel Research Group, and is a founder of QuesTek Innovations LLC, a materials design company that was selected for Fortune magazine’s list of the 25 breakthrough companies of 2005. He is a member of the National Academy of Engineering and a fellow of ASM and TMS-AIME. He has authored more than 250 publications. He received a BS and MS in 1970 and ScD in 1974 in materials science from MIT and remained there in a series of senior research positions before joining the faculty of Northwestern in 1988. Beyond materials design, his research interests include phase transformations, structure/property relations, and applications of high resolution microanalysis. Recent awards include the ASM Campbell Memorial Lectureship, the TMS-SMD Distinguished Scientist/Engineer Award, the Cambridge University Kelly Lectureship, and the ASM Gold Medal.
