Dr. Gamble specializes in the analysis and testing of fluid structure interactions (FSI) which incorporates multi-disciplinary knowledge across the fields of mechanical engineering and fluid mechanics. Her experience extends to both computational methods, such as finite element analysis (FEA) and computational fluid dynamics (CFD), in addition to experimental methods and validation. She has extensive experience in data acquisition of multi-physics problems, 3D printing and additive manufacturing, and wind tunnel testing. Her breadth of experience also extends to vibration testing, unmanned aerial vehicle (UAV) wing design and analysis, smart and shape memory material applications, composite materials, and digital imaging. She has applied her expertise in these areas to projects on modal analysis of 3D printed piezoelectric sensors, and morphing aero-control devices in aircraft and automobiles.

Prior to joining Exponent, Dr. Gamble’s postdoctoral research at the University of Michigan experimentally and computationally investigated the load-alleviation properties of bird-inspired flexible wings. During this research, she developed a custom FSI framework to model geometrically nonlinear structures interacting with fluids and verified it using commercial software (Ansys). Through cross-disciplinary collaborations, Dr. Gamble also conducted vibration testing and static wind tunnel testing on a 3D printed feather sensor with piezoresistive and piezoelectric sensing capabilities to characterize the sensor’s performance. She incorporated her passion for photography and digital imaging into these experiments by designing a stereo photography test setup to visually measure the aero-structural coupling of the sensor under aerodynamic loads. During her postdoctoral fellowship, she also co-taught “Introduction to Solid Mechanics and Aerospace Structures”.

Dr. Gamble’s graduate research at the University of Michigan further drew inspiration from birds to identify ways in which gliding UAVs could operate with improved efficiency and maneuverability by developing and analyzing bioinspired morphing aircraft. She redesigned traditional aircraft control surfaces using novel bioinspired morphing mechanisms which were actuated using piezoelectric composites and shape memory alloys. She experimentally and numerically analyzed their aero-structural performance and control effectiveness. Dr. Gamble also numerically modeled the response of piezoelectric composites using finite element software (Abaqus). Her graduate degree included experience in structural dynamics, fluid dynamics, composites, and finite element methods. She has also worked on developing similar active morphing control surfaces for automotive applications.
