  1. PROJECTS WITH POTENTIAL FUNDING 1-TÜBİTAK 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) Bending test of helicopter blade Dynamic mechanical analysis

  2. (PreVabs-Vabs beam section analysis codes, Samcef Wind Turbine/Focus wind turbine system multi body analysis codes, Samcef and Nastran FE codes) PROJECTS WITH POTENTIAL FUNDING 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.
