Dr. Giachetti has experience solving technical problems in a variety of industries including product development, evaluation, assistance with recalls, and mechanical performance of systems. His academic emphasis included topics in mechanics of materials, non-linear continuum mechanics, non-linear dynamics, vibrations, and finite element analysis. His background in mechanics and instrumentation allows him to easily build and monitor complex systems in order to assess their functionality. These systems have ranged from wire ropes, cookware, and child carriers to transducers and railcars.
Prior to joining Exponent, Dr. Giachetti worked in industry designing steel coiling machinery and overhead lifting devices; including tongs, beams, and hooks. While performing his graduate research, he worked in the Biomechanics laboratory at the University of Illinois investigating factors which increase the contact stresses between adjacent components in total knee replacements through three dimensional computer modeling and finite element analysis. His doctoral research in the University of Wisconsin’s Biomechanics Laboratory involved characterizing the underlying control strategy of bipedal stability based on the end-point force output of the lower limbs.
Dr. Giachetti has extensive experience utilizing LabView to create specialized data acquisition solutions that implement multiple, simultaneous sensing technologies for real-time analysis. His acquisition solutions have included accelerometers, potentiometers, thermocouples, GPS devices, pressure transducers, force plates, and low-cost web cams. This technology has been used in various ways, including: two-dimensional optical motion capture, vibrational analysis, and temperature acquisition.
Dr. Giachetti also has extensive experience utilizing AutoCAD, Ansys, Matlab, Mathcad, EES, and 3DSSPP.
