Biography

Dr. Berke studies the mechanical characterization of solids and structures in challenging environments, and at high temperatures in particular. He is especially interested in the role that environment plays on a material's ability to withstand heterogeneous failure mechanisms such as fracture, fatigue, and creep. His lab uses advanced imaging techniques to extract full-field, in situ deformation and strain measurements across temperature, time, and length scales.

Teaching Interests

MAE 3040: Mechanics of Solids | MAE 5040: Experimental Solid Mechanics | MAE 6060/6061: Micro-Mechanisms of Deformation and Failure | Mentoring of Undergraduate and Graduate Student Researchers | Broadening Participation of Underrepresented Groups in Engineering

Research Interests

Solid Mechanics: Thermo-mechanical loading, fracture, fatigue, creep, environmental effects. | Advanced Material Systems: High temperature materials, multi-scale structures, advance energy systems, aerospace vehicles, nuclear structural materials, accident tolerant fuels. | Experimental Methods: High temperature measurements, in-situ methods, resonant ultrasound microscopy, 2-D and 3-D digital image correlation, vibration-based fatigue testing, high-throughput techniques.
