Talk Title: Mechanics of Materials at Extreme Environment, at Different Time and Length Scale: A Digital Image Based Approach

Series: Aerospace and Mechanical Engineering Seminar Series

Abstract: Understanding the failure mechanism of materials at extreme condition is essential and at the same time challenging. There have been different approaches proposed over the years to studying materials response at extremely aggressive environment, for example high pressure, ultrahigh temperature. With the advent of high speed imaging systems and computer processing power, these days, high quality images can be taken as fast as 200 million frames / sec and one can study the failure mechanisms at such a high events by carefully analyzing the digital images taken during testing. We used a digital image based approach and characterize the deformation mechanism of materials at different loading conditions, at different time and length scale and temperature. In this talk, different examples such as, shock loading of rigid foams and pre-stressed composite, local heterogeneity in polycrystalline materials and deformation of materials at temperature above 1000°C will be presented.

Biography: Addis Kidane is an assistant professor of Mechanical Engineering at the University of South Carolina. He got his Ph.D. from the University of Rhode Island in 2009 and spent 2 years at California Institute of Technology as a postdoctoral scholar before he moved to Columbia. His research interests are in the areas of failure and fracture of materials at extreme conditions, functionally graded materials, digital image based experimental analysis. He is a recipient of the 2013 Haythornthwaite Research Initiation Grants, from the ASME Applied Mechanics Division and the 2014 AFOSR Young Investigator Research Program (YIP) award.
