Dr. Michael D. Sangid

Michael D. Sangid received his degrees in Mechanical Engineering from the University of Illinois at Urbana-Champaign (UIUC): B.S. in 2002 with a minor in Mathematics, M.S. in 2005, and PhD in 2010. During his undergrad, he worked in the Advanced Materials Testing and Evaluation Laboratory and also the Autonomic Materials Laboratory in the fields of material behavior and testing.  His master’s research focused on Process Characterization of Vibrostrengthening and Application to Fatigue Enhancement of Aluminum Aerospace Components and was sponsored by the Boeing Corporation.  After completing his Master’s degree, Dr. Sangid spent two years working in Indianapolis, IN for Rolls-Royce Corporation, specializing in material characterization, deformation, fatigue, fracture, and creep of high temperature aerospace materials before resuming his education in 2007.  His research has centered around a multi-scale approach to understand grain boundary effects on crack initiation.  Through this work, atomistic simulations are used to quantify local energy barriers to deformation, which are built into continuum models to connect material structure to performance.  Dr. Sangid continued as a Postdoctoral Research Associate at UIUC working on 1.) heterogeneous deformation of materials and fatigue crack growth testing and modeling of new and emerging materials and 2.) prediction of fiber orientation and length in polymer-based long fiber composites. 

In the fall of 2011, Dr. Sangid started as an Assistant Professor at Purdue University in the School of Aeronautics and Astronautics, where he continues his work on building computational materials models with experimental verification and validation efforts.  His research specifically focuses on (micro)structure to performance modeling, via using atomistic simulations to inform multi-scale models for plasticity, fatigue, and fracture of metallic alloys and high temperature composites.  Both material systems have direct applications in Aerospace Engineering.  There is also an experimental component to his research as he does advanced materials testing and characterization including digital image correlation, advanced microscopy, and stress analysis using high-energy x-ray diffraction at the synchrotron source at Argonne National Lab.  This research lies at the confluence of materials science and solid mechanics.  Dr. Sangid is an active member of the Minerals, Metals, & Materials Society; American Society of Mechanical Engineers; American Institute of Aeronautics and Astronautics; ASM International; and Pi Tau Sigma Honor Society of Mechanical Engineers.
