  • Crack Detection in Aluminum Structures 

    Butrym, Brad A. (Virginia Tech, 2010-04-26)
    Structural health monitoring (SHM) is the process of using measurements of a structureâ s response to known excitations and trying to determine if damage has occurred to the structure. This also fits the description of ...
  • Design, Simulation, and Wind Tunnel Verication of a Morphing Airfoil 

    Gustafson, Eric Andrew (Virginia Tech, 2011-05-25)
    The application of smart materials to control the flight dynamics of a Micro Air Vehicle (MAV) has numerous benefits over traditional servomechanisms. Under study is wing morphing achieved through the use of piezoelectric ...
  • Macro Fiber Composite Actuated Unmanned Air Vehicles: Design, Development, and Testing 

    Bilgen, Onur (Virginia Tech, 2007-05-10)
    The design and implementation of a morphing unmanned aircraft using smart materials is presented. Articulated lifting surfaces and articulated wing sections actuated by servos are difficult to instrument and fabricate in ...
  • Nonlinear Mechanical and Actuation Characterization of Piezoceramic Fiber Composites 

    Williams, Robert Brett (Virginia Tech, 1999-06-17)
    The use of piezoelectric ceramic materials for structural actuation is a fairly well developed practice that has found use in a wide variety of applications. However, actuators with piezoceramic fibers and interdigitated ...
