An analytical model is developed to study the stress response and the yielding of rotating functionally graded hollow shafts in the framework of generalized plane strain. The modulus of elasticity and the uniaxial yield limit of the shaft material are assumed to vary radially in nonlinear forms. It is shown that different modes of plasticization may take place. Analytical expressions for the critical values of the material parameters leading to different modes of plastic deformation and the corresponding elastic limit rotation speeds are derived by the use of Tresca's yield criterion.

The effect of strain rate and temperature on forming limit diagram for DKP-6112 and AZ31 materials Goksen, Seckin; Darendeliler, Haluk (2020-01-01) Forming limit diagrams (FLDs) are used in sheet metal operations widely for predicting blank fracture and forming characteristics of materials. There are three approaches for building forming limit diagrams which are the experimental, theoretical and numerical methods. Experimental method, which includes Nakazima formability test, is generally preferred for determining forming limit diagrams, although it requires complex experimental setup and effort. This study, firstly, compares the experimentally determi...
The effects of tine coupling and geometrical imperfections on the response of DETF resonators Azgın, Kıvanç (IOP Publishing, 2013-12-01) This paper presents a two-degree-of-freedom analytical model for the electromechanical response of double ended tuning fork (DETF) force sensors. The model describes the mechanical interaction between the tines and allows investigation of the effect of a number of asymmetries, in tine stiffness, mass, electromechanical parameters and load sharing between the tines. These asymmetries are introduced during fabrication (e. g., as a result of undercut) and are impossible to completely eliminate in a practical d...
The free-end interface crack problem for bonded orthotropic layers Kadıoğlu, Fevzi Suat (1995-01-01) The plane elasticity problem of two bonded orthotropoic layers containing cracks perpendicular to and along the interface is considered. The cracks are extended to intersect the boundaries and each other in such a way that a crack configuration suitable to study the edge debonding problem associated with bonded dissimilar materials is obtained. The problem is reduced to the solution of a system of singular integral equations with Cauchy type singularities. Numerical results for stress intensity factors and ...
Evaluation of a new turbulence model for boundary layer flows with pressure gradient Marangoz, Alp; Çıray, Cahit; Department of Aerospace Engineering (2005) In this thesis, a new turbulence model developed previously for channel and flat plate flows is evaluated for flat plate flows with pressure gradient. For this purpose a flow solver, which uses boundary layer equations as the governing equations and Von Karman momentum integral equation for the calculation of skin friction, is developed. It is shown that the error of the new turbulence model, in predicting the velocity profile, is less than 5 % for the flat plate flows without pressure gradient and less tha...
Determining the optimal parameters for the MHD flow and heat transfer with variable viscosity and Hall effect EVCİN, CANSU; Uğur, Ömür; Tezer, Münevver (2018-09-15) The direct and optimal control solution of the laminar, fully developed, steady MHD flow of an incompressible, electrically conducting fluid in a duct is considered together with the heat transfer. The flow is driven by a constant pressure gradient and an external uniform magnetic field. The fluid viscosity is temperature dependent varying exponentially and the Hall effect, viscous and Joule dissipations are taken into consideration. The control problem is solved by the discretize-then-optimize approach usi...
