Master Thesis Modeling and Analyses of Pretwisted Beams Having Piezoelectric Smart Materials(Izmir Institute of Technology, 2017) Akari, Merve; Yardımoğlu, BülentIn this study, modeling and analyses of pretwisted beams having piezoelectric smart materials are acomplished by using Finite Element Method. A computer program is developed by using APDL (ANSYS Parametric Design Language) in ANSYS with SOLID45 and SOLID5 for pretwisted beam and piezoelectric layer, respectively. The effects of the pretwist angle on electric field are analyzed.Master Thesis Vibration Analysis of a Giromill-Type Vertical Axis Wind Turbine(Izmir Institute of Technology, 2013) Akgüneyli, Melih; Yardımoğlu, BülentVibration characteristics such as natural frequencies and mode shapes of Giromill-type vertical axis wind turbines (VAWTs) with different design parameters are studied by Finite Element Method (FEM). As design parameters, length of the blade, thickness of the blade and the support distance of the blade are considered. On the other hand, local wind characteristics are considered for aerodynamic calculations. The well known commercial software package, ANSYS, is used for finite element analysis. Aerodynamic loads and centrifugal forces are taken into account in calculating the natural frequencies. In order to see the interactions of the parameters of the VAWT, seven models are obtained by modification of model I which is a reference model. Vibration characteristics of all models are found. The obtained results are presented in tabular forms.
