  • A novel approach to thermal and mechanical stresses in a fgm with cylinder exponentially-varying properties 

    Çelebi, Kerimcan; Yarımpabuç, Durmuş; Keleş, İbrahim (POLISH SOC THEORETICAL & APPLIED MECHANICS., 2017)
    A novel approach is employed to a general solution for one-dimensional steady-state thermal and mechanical stresses in a hollow thick cylinder made of a functionally graded material (FGM). The temperature distribution is ...

  • Numerical solutions of the mrlw equation using moving least square collocation method 

    aplan, Ayşe Gül; Dereli, Yılmaz (ANKARA UNIV., 2017)
    In this paper, the Modified Regularized Long Wave (MRLW) equation is solved by using moving least square collocation (MLSC) method. To show the accuracy of the used method several numerical test examples are given. The ...

  • A new method for (4+1) dimensional fokas equation 

    Demiray, Şeyma Tülüce; Bulut, Hasan (E D P SCIENCES., 2018)
    In this paper, modified exp (-Omega(xi))-expansion function method (MEFM) has been tackled for procuring exact solutions of (4+1) dimensional Fokas equation. Hyperbolic function solutions and dark soliton solutions of (4+1) ...

  • Curves of constant breadth according to darboux frame in galilean spaceG(3) 

    Bozok Gün, Hülya (UNIV NIS., 2019)
    In this work, the curves of constant breadth according to Darboux frame in the 3-dimensional Galilean Space are investigated. Firstly the curves of constant breadth according to Darboux frame are determined then the ...

  • Polynomial affine translation surfaces in euclidean 3-Space 

    Bozok Gün, Hülya; Ergüt, Mahmut (SOC PARANAENSE MATEMATICA, 2019)
    In this paper we study the polynomial affine translation surfaces in E-3 with constant curvature. We derive some non-existence results for such surfaces. Several examples are also given by figures.

  • Elastic Solution Based On The Mori-Tanaka Sceheme For Pressurized Functionally Graded Cylinder 

    Eker, Mehmet; Yarımpabuç, Durmuş; Yıldırım, Ali; Çelebi, Kerimcan (CZESTOCHOWA UNIV TECHNOLOGY, 2020)
    In this paper, an elastic analysis of a thick-walled functionally graded cylinder subjected to internal pressure is examined. Material properties for the isotropic material are estimated to obey the Mori-Tanaka homogenization ...

  • A Spectral solenoidal-galerkin method for rotating thermal convection between rigid plates 

    Yıldırım, Cihan; Yarımpabuç, Durmuş; Tarman, Hakan I. (HINDAWI LTD, 2013)
    The problem of thermal convection between rotating rigid plates under the influence of gravity is treated numerically. The approach uses solenoidal basis functions and their duals which are divergence free. The representation ...

  • Semigroup presentation for congruences on groups 

    Ayık, Gonca; Çalışkan, Basri (KOREAN MATHEMATICAL SOC, 2013)
    We consider a congruence rho on a group G as a subsemigroup of the direct product G x G. It is well known that a relation rho on G is a congruence if and only if there exists a normal subgroup N of G such that rho = {(s, ...

  • Curves of constant breadth according to type-2 bishop frame in E3 

    Gün Bozok, Hülya; Sepet, Sezin Aykurt; Ergüt, Mahmut (ANKARA UNIV., 2017)
    In this paper, we study the curves of constant breadth accordingto type-2 Bishop frame in the 3-dimensional Euclidean SpaceE3. Moreoversome characterizations of these curves are obtained.

  • Forced vibration analysis of inhomogeneous rods with non-uniform cross-section 

    Çelebi, Kerimcan; Baran, Tarık (Academic Publication Council, 2018)
    Forced vibration analysis of cantilever rods is presented that have material properties and cross-section areas that arbitrarily vary in the axial direction, solved using Laplace transform in time domain and complementary ...

  • Fuzzy normed rings 

    Aykut, Emniyet; Şahin, Mehmet (MDPI AG, 2018)
    In this paper, the concept of fuzzy normed ring is introduced and some basic properties related to it are established. Our definition of normed rings on fuzzy sets leads to a new structure, which we call a fuzzy normed ...
