    • Advanced linear methods for T–tail aeroelasticity 

      Van Zyl, Louwrens Hermias (North-West University, 2011)
      Flutter is one of the primary aeroelastic phenomena that must be considered in aircraft design. Flutter is a self-sustaining structural vibration in which energy is extracted from the air flow and transferred to the ...
    • Quadratic mode shape components from ground vibration testing 

      Van Zyl, L.H.; Mathews, E.H. (ASME, 2012)
      Points on a vibrating structure generally move along curved paths rather than straight lines. For example, the tip of a cantilever beam vibrating in a bending mode experiences axial displacement as well as transverse ...
    • Quadratic mode shape components from linear finite element analysis 

      Van Zyl, L.H.; Mathews, E.H. (ASME, 2012)
      Points on a vibrating structure move along curved paths rather than straight lines; however, this is largely ignored in modal analysis. Applications where the curved path of motion cannot be ignored include beamlike ...
