PROJECTS WITH POTENTIAL FUNDING

• 1- TÜBITAK 1001 Project Determination of the
  bending-twisting coupling in composite structures
  via digital image correlation (DIC) method and
  exploiting bending-twisting coupling in turbine
  blades for passive load control in horizontal
  axis wind turbines
• Required students 2
• 1st Student Testing of composite plates and
  composite box beams to determine the
  bending-twisting coupling effect of off-axis
  plies via digital image correlation. Comparisons
  will be made with finite element method. Also
  includes material coupon testing to determine
  elastic properties to use in FE analysis. Dynamic
  mechanical analysis tests to determine material
  damping. (Aramis DIC system, MTS/Dartec testing
  machines, HBM strain gage measurements, DMA, FE
  analysis with Nastran)

• 2nd Student Design of a reference wind turbine
  blade to be used in multi-body simulations of the
  wind turbine system. Multi-body transient
  aeroelastic analysis of wind turbine system to
  study the effect of bending-twisting coupling
  induced on the composite blades on the load
  alleviation in the wind turbine system.
