PROJECTS WITH POTENTIAL FUNDING
1- TÜBÄ°TAK 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)
Dynamic mechanical analysis
Bending test of helicopter blade

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.

analysis codes, Samcef and Nastran FE codes)

2- SANTEZ PROJECT with Dr. Gürses, Dr. Çoker and TEI
Development of advanced bolted flange design and analysis tool
Required students: 1 ( 2 more for Dr. Gürses and Dr. Çoker)
Evaluation of finite element and test results on friction, contact and bolt torque - preload and design a bolted
flange design and analysis tool interface (ANSYS FE code)
Input: Flange type, geometry (geometric tolerances, surface roughness etc.) number of bolts (type, preloadtorque relation), friction coefficient, material, loads(thermal, axial, shear force, bending moment, torque,
working conditions (dry, with oil, temperature), fatigue loads
Output: Strength (flange and bolt), life, separation and slippage
