Our Tuesday April 11th, 2017 Chapter Dinner Meeting:

Topic: Damage Tolerant Metals For Extreme Environments


While material failure has been studied for many years, our current ability to predict and simulate evolving damage in the extreme environments of high stress and high strain rate loading remains limited. This is particularly problematic because material and component failure under these types of dynamic loading conditions can often lead to catastrophic consequences. One reason for this limited predictive capability is the lack of understanding of the linkages between the process-induced as well as the evolved microstructure and damage.  To this end, within the Materials Science in Radiation and Dynamic Extremes Group (MST-8) at Los Alamos National Laboratory, the role of microstructure on the early stages of damage has been studied in a number of metals and alloys using a combination of small scale experiments and simulations.   These multi-length scale studies have identified a number of deterministic linkages between damage nucleation, damage growth and microstructural features such as: inclusion/metal interface characteristics, bi-metal interfaces, grain boundary types, grain boundary orientation, and grain orientation. Here, the tools utilized to advance predictive models for damage and failure in extreme environments as well as the work to design next generation materials for enhanced properties, particularly damage tolerance, will be discussed.  

Speaker: Ellen Cerreta, MST-8, Los Alamos National Laboratory,


Ellen Cerreta is the Deputy Division Leader for The Explosive Science and Shock Physics Division, at Los Alamos National Laboratory.  She joined Los Alamos as a Post Doctoral Associate in 2001. Ellen received her BS in Aerospace Engineering from The University of Virginia and her Ph.D. in Materials Science and Engineering from Carnegie Mellon University.  Since coming to Los Alamos, she has focused on the correlation of microstructure to mechanical response of metals and alloys, with the support of the Office of Basic Energy Sciences, the national defense, global security, and energy programs, and Laboratory Directed Research and Development (LDRD).  Her research has had a focus on material behavior in dynamic loading environments.  Ellen is an adjunct faculty member in The Institute of Shock Physics at Washington State University and she joined the ASM Board of Trustees in October of 2015.  In 2016, she was awarded ASM Fellow.
