Materials Response Under Extreme Conditions

Many engineering materials exhibit fascinating behaviors under extreme loading/environmental conditions such as high pressure, high temperature, and high rate of deformation, with some of these responses being quite counter intuitive. Such information is crucial for defense-related applications seeking to improve the effectiveness of combat and protective systems, such as body armor, vehicle armor, and hard concrete structures.

Dr. Xu Nie is a professor in the Department of Mechanical Engineering at SMU-Lyle. He received his Ph. D. from the School of Materials Engineering at Purdue University where he also conducted post-doctoral research in the School of Aeronautics and Astronautics.

Dr. Nie's current research is focused on the dynamic and multi-scale impact damage characterization/evolution in heterogeneous cementitious composites, advanced diagnostic techniques for Kolsky bars, and high-rate mechanical response and microstructural evolution of advanced metallic alloys.

Dr. Nie has authored/co-authored over 30 journal articles in the broad area of Impact Mechanics and Dynamic Behavior of Materials. To date, he has received over $1.3 Million in research funding from multiple DOD and DOE agencies such as Sandia National Laboratories (SNL), Air Force Research Laboratory (AFRL), and the U.S. Army Engineer Research and Development Center (ERDC). Dr. Nie has been a summer visiting professor at AFRL. Munition Directorate, Eglin AFB, FL since 2014.
