In this study, propagation of transient dilatational waves in a viscoelastic cylinder contained in an elastic case is investigated. The viscoelastic material of the cylinder is modelled as standard linear solid. The encased viscoelastic cylinder is subjected to uniform time dependent dynamic inputs at its inner and outer boundaries. Method of characteristics is employed to obtain the solutions. Solutions for the case of an ablating inner surface are obtained as well. The numerical results are displayed in curves denoting the variations of circumferential and radial stresses with time at different locations. The curves reveal clearly the effects of reflections and refractions at the inner and outer surfaces and the interface between the viscoelastic cylinder and the elastic case. Furthermore, the effects of damping, geometric dispersion and ablating inner boundary are clearly seen in the curves.

Transient dynamic response of viscoelastic cylinders enclosed in filament wound cylindrical composites
Şen, Özge; Turhan, Doğan; Department of Engineering Sciences (2005)
In this study, transient dynamic response of viscoelastic cylinders enclosed in filament wound cylindrical composites is investigated. Thermal effects, in addition to mechanical effects, are taken into consideration. A generalized thermoelasticity theory which incorporates the temperature rate among the constitutive variables and is referred to as temperature-rate dependent thermoelasticity theory is employed. This theory predicts finite heat propagation speeds. The body considered in this thesis consists o...
Transient dynamic shear response of filament wound cylindrical composites
Turhan, D; Ghaith, M (1999-06-10)
In this study, transient dynamic response of filament wound cylindrical composites subjected to shear tractions is investigated. The cylindrical composite consists of n different layers. Layers with different winding angles are modelled as orthotropic, homogeneous and linearly elastic materials. The cylindrical composite is subjected to uniform time dependent shear tractions at its inner surface and the outer surface is free of surface tractions. The composite body is assumed to be initially at rest. The go...
Theoretical investigation of intersubband nonlinear optical rectification in AlxlGa1-xlAs/GaAs/AlxrGa1-xrAs asymmetric rectangular quantum wells
Karabulut, Ibrahim; Atav, Uelfet; Safak, Haluk; Tomak, Mehmet (Wiley, 2007-09-01)
In this study, a theoretical investigation of intersubband nonlinear optical rectification in Alx1Ga1-x1As/ GaAs/AlxrGa1-xrAs asymmetric rectangular quantum wells is presented. The electronic states in the asymmetric rectangular quantum well are described within the framework of the envelope function approach including the effects of band nonparabolicity and the effective mass mismatch. The nonlinear optical rectification is calculated using the density matrix formalism. It is found that the nonlinear optic...
Nonlinear vibrations of curved single and doublewalled carbon nanotubes /
Samandari, Hamed; Ciğeroğlu, Ender; Department of Mechanical Engineering (2014)
In this thesis, effects of Geometric, initial curvature, and van der Waals (vdW) interlayer force nonlinearities on the variation of nonlinear natural frequency of Carbon Nanotubes (CNTs) are investigated in detail throughout several case studies. Galerkin method with a single trial function, which is the eigenfunction of the linear system, is widely used in literature in studying nonlinear vibrations of CNTs. However, eigenfunctions of the nonlinear systems can be significantly different than the eigenfunc...
Transient waves in viscoelastic cylindrical layered media
Abu Alshaikh, I; Turhan, D; Mengi, Y (2002-09-01)
Propagation of two-dimensional transient waves in viscoelastic cylindrical layered media is investigated. The cylindrical multilayered medium consists of N different isotropic, homogeneous and linearly viscoelastic layers with two discrete relaxation times. A numerical technique which combines the complex Fourier series with the method of characteristics is employed to obtain the solutions. The numerical results are displayed in curves denoting the variations of the stress and displacement components with t...
