Dr. Kennett specializes in failure analysis, failure prevention, materials science, physical and mechanical metallurgy, assessment of engineering structures, and fracture mechanics. Dr. Kennett received his Ph.D. in Metallurgical and Materials Engineering from Colorado School of Mines in 2014 and his Bachelor of Science in Mechanical Engineering from University of North Florida in 2010. He has experience with a wide range of applications and industries, including surgical devices, medical implants, microelectronics, oil and gas pipelines and refineries, automotive safety equipment, and raw material production. In these industries, Dr. Kennett has studied material characterization, mechanical behavior, high and low temperature performance, machine design, product life assessment, and product design. Additionally, he continues to research the effects of processing on the microstructure and subsequent mechanical properties of different commercial grades of steel.

Prior to joining Exponent, Dr. Kennett conducted his Ph.D. dissertation work at Colorado School of Mines (CSM) in the Advanced Steels Processing and Products Research Center. During his studies at CSM, he studied the effects of the martensitic packet size, block size, lath size, dislocation density, and alloy precipitation on the mechanical properties of martensitic steel. To investigate these effects, he performed extensive amounts of characterization using optical microscopes (OM), scanning electron microscopes (SEM), focused ion beam microscopes (FIB), transmission electron microscopes (TEM), and X-ray diffractometers (XRD). During his time at CSM, he also studied the microstructure of CoCrMo hip implants, ferrite-pearlite steels, carburized steels, and cold sprayed copper and aluminum systems. In addition to his studies, he was responsible for the operation, maintenance, training, and data interpretation of different mechanical testing techniques and equipment, including the Gleeble® advanced thermo-mechanical simulator. The Gleeble® is a research tool that can be used to simulate high heating and cooling rates, elevated temperature deformation, and perform controlled heat treatments to create specific microstructures.

Dr. Kennett also has experience with machine design; specifically, the design and implementation of custom machines used for unique testing scenarios, i.e., a rolling sliding contact fatigue machine. This machine is currently located at CSM and is actively used by graduate students. In addition to mechanical design, Dr. Kennett has experience with the design, implementation, and optimization of closed and open-loop control systems. These systems were developed and used for 6-axis robotic arms and underwater remotely operated vehicles.
