Dr. Briant specializes in solid mechanics, finite element analysis, mechanical engineering, biomechanics, and digital image processing. Dr. Briant has applied his expertise to numerous design analysis and failure analysis problems while at Exponent. He has extensive experience with finite element analysis of medical devices, and he has assisted numerous medical devices companies with both numerical and experimental testing and analysis in preparation for FDA submission. In addition, he has performed many static and dynamic finite element analyses across a wide array of scales, ranging from consumer electronic components to large piping systems undergoing water hammer events.
Dr. Briant has also assisted in a wide range of both litigation and non-litigation mechanical engineering failure analysis cases. These cases include corrosion of fire hydrant components, injury analysis cases, and failure of large dynamic structures. In addition, he has experience with digital image processing and has written algorithms for both military and non-military applications.
Prior to joining Exponent, Dr. Briant’s research focused on laboratory and numerical analysis of cartilage tissue mechanics, as well as the design and analysis of orthopaedic biomedical devices. He also has experience using lathes, milling machines, and other shop equipment, and participated in the design and fabrication of Washington University’s entry to the Formula Society of Automotive Engineers racecar competition.
