It currently houses unique equipment valued in excess of $4.5M, and has been used by his research group (and others) in areas ranging from advanced aerospace materials to nuclear and biomedical systems. Research and teaching interests are primarily in the areas of processing/structure/property relationships in ferrous and non-ferrous engineering materials; effects of superposed pressure on deformation/fracture; fatigue and fracture of intermetallics and composites, bulk metallic glass, and layered/laminated materials; deformation processing; blast-resistant materials; advanced engineered materials systems; fracture and fatigue behavior of biomedical materials; failure analysis; additive manufacturing. Publications and presentations exceed 300 and 900, respectively, with an H-index > 50. His top 50 papers have been cited over 6,000 times with recent major reviews on Additive Manufacturing, Fracture and Fatigue of Materials used in Biomedical Applications, and Metal Matrix Composites. His recent Nature Materials (NM) paper on metallic glasses was selected for a News and Views Article in NM; was selected as an Editor's Choice Paper in Science; and was selected by NM editors as one of the twenty most influential papers published in NM from 2002-2012.
His B.S., M.E., and Ph.D. were in Metallurgical Engineering and Materials Science at Carnegie Mellon University as a HERTZ Foundation Fellow. His M.E. research was on hydrogen embrittlement of austenitic stainless steels. Ph.D. research focused on hydrogen embrittlement and fracture of rail steels. He also spent two years as Metallurgical Engineer/Failure Analyst at the Richmond Refinery Materials Laboratory, CHEVRON USA. He subsequently spent two years as a NATO/NSF Postdoctoral Fellow in the Department of Materials Science and Metallurgy at Cambridge University, England, working with Prof. John F. Knott, FRS, OBE, on fracture and fatigue of engineering materials. Specific research projects included: stress relief embrittlement and fracture/fatigue of 2 1/4 Cr-1 Mo steels; Pb-induced solid metal embrittlement of aluminum alloy pressure vessels; and impurity effects on fracture of Al-Li alloys.
He joined CWRU as Assistant Professor of Materials Science and Engineering in 1986 and is currently the Arthur P. Armington Professor of Engineering II, Director of the Advanced Manufacturing and Mechanical Reliability Center, and Professor of Mechanical and Aerospace Engineering. He has received a number of national and international awards for research and teaching. In research, he received the Allegheny Int'l Research Fellowship (CMU), HERTZ Foundation Graduate Fellowship (CMU), NATO/NSF Postdoctoral Fellowship and ALCAN Fellowship for Research (Cambridge University), NSF Presidential Young Investigator Award, ASM Research Silver Medal, Charles Hatchett Award from the Institute of Metals (U.K.) for work on Nb, and was elected an Overseas Fellow at Churchill College, Cambridge University, where he spent a sabbatical year for 2003-04. He received a Meritorious Service Award by the Case Alumni Association (CAA) in 2008, the Case School of Engineering (CSE) Research Award in 2005 and 2009, and the TMS Leadership award in 2014.
In the area of teaching and mentoring, he has advised 71 MS students and 27 Ph.D. students, in addition to 50 post-doctoral, visiting scholars, and staff. He has received the CTSC Technical Educator Award, SAE Ralph R. Teetor Educational Award, ASM Bradley Stoughton Award for Young Teachers, and the John S. Diekhoff Award for Graduate Teaching and Mentoring at CWRU. He has served on a number of panels organized by the NSF, National Research Council/National Academy of Sciences as well as the Institute of Mechanics and Materials at UC San Diego. He is on the editorial board of four journals and has co-organized over 30 conferences, including one Gordon Conference on Physical Metallurgy. He was elected Fellow of ASM in 1995 and is past Chair of ASM/TMS Joint Composites Committee.

Talk Title: Mesoscale Modeling of Fatigue Crack Growth
Alan Needleman completed his Ph.D. in Engineering at Harvard University in 1970. He then spent five years in Applied Mathematics at MIT before moving to Brown University where he became Florence Pirce Grant University Professor in 1996. He retired from Brown in June 2009 and moved to the Materials Science and Engineering Department at the University of North Texas (UNT).

In January 2015 he left UNT and is now a University Distinguished Professor and a TEES Distinguished Research Professor in the Department of Materials Science and Engineering at Texas A&M University. His contributions include the development of a ductile fracture computational methodology, the development of cohesive surface methods for fracture analysis and creation of a framework that enables using discrete dislocation plasticity to solve general boundary value problems. Professor Needleman was awarded a Guggenheim Fellowship in 1977, and is a member of the National Academy of Engineering and of the American Academy of Arts and Sciences. He has been awarded the Prager Medal by the Society of Engineering Science, the Drucker and Timoshenko Medals by the American Society of Mechanical Engineers. Professor Needleman also holds honorary doctorates from the Technical University of Denmark and Ecole Normale Superior de Cachan (France), and is an Honorary Professor of Dalian University of Technology (China).

Talk Title: Model reduction strategy applied to a problem of crack propagation in anisotropic materials
Sylvie Pommier completed her Ph.D. in Engineering at Ecole Centrale Paris in 1995. She then spent 8 years at Ecole Centrale Paris as a faculty member (1995-2003) before moving to Ecole normale supérieure Paris-Saclay, in 2003, to become a Professor in Mechanical Engineering.

She produced over 150 publications related to fatigue crack growth and related problems and was the supervisor or co-supervisor of 25 PhD students in the field. Her contributions includes the development of life prediction methods in non-linear conditions (inelastic material behaviour, non-isothermal loading conditions, mixed mode crack growth in non-linear conditions, contact mechanics and fretting-fatigue) for aerospace, energy and naval applications. She is currently developing approaches based on principal components analysis and the thermodynamics of irreversible processes. This method allows to model crack growth as well as Fretting-fatigue, as it is done for the modeling of the non-linear behavior of the materials, but with a formalism based on non-local state variables tailored for characterizing the non-linear behavior of the material around moving singularities such as crack fronts or contact fronts with the minimum possible independent degrees of freedom.
From 2009 to 2012 she was the director of the doctoral School of ENS Cachan (now known as ENS Paris-Saclay). From 2012 to 2014 she was vice-president of ENS Cachan in charge of research and doctoral training. From sept. 2014 she was the project leader for setting up the framework of doctoral research at Université Paris-Saclay and she is now the dean of doctoral research of Université Paris-Saclay since March 2016. Université Paris-Saclay is a union of 18 member institutions (including ENS Cachan, Université Paris-Sud, Ecole Polytechnique …) which is now accredited for delivering the doctorate degree award. Sylvie Pommier is coordinating the activity of 20 doctoral schools, which are organizing the recruitment, follow up, training and assessment of 5400 PhD students in various fields, from maths and computer sciences, to social sciences and finance, including life sciences and engineering sciences. She is also president of the national monitoring committee for L.M.D in France.
