The problem of thermoelastic contact for the homogenous isotropic half-plane with a sliding rigid flat punch problem is investigated. As the rigid flat punch is assumed to slide over the surface of the material, heat is generated due to the friction between the punch and a surface. This heat causes the change of material thermoelastic properties and this change is taken into account in this work by using temperature dependent material properties. In order to obtain the steady state solution, frictional heat in the contact surface must be in equilibrium. Hence, an iterative code is developed and implemented to solve this problem by using finite element analysis. The steady state results for the contact of homogenous isotropic half-plane with a rigid flat punch are obtained. Moreover, comparative study is made for the contact stress and temperature distributions.

Analysis of Lossy Dielectric Objects with the Multilevel Fast Multipole Algorithm Ergül, Özgür Salih (2011-07-08) Rigorous solutions of electromagnetics problems involving lossy dielectric objects are considered. Problems are formulated with two recently developed formulations, namely, the combined-tangential formulation (CTF) and the electric and magnetic current combined-field integral equation (JMCFIE), and solved iteratively using the multilevel fast multipole algorithm (MLFMA). Accuracy and efficiency of solutions are compared for different objects and conductivity values. We show that iterative solutions of CTF a...
Investigation of nonplanar perfectly matched absorbers for finite-element mesh truncation Kuzuoğlu, Mustafa (1997-03-01) In this paper, we present a detailed theoretical and numerical investigation of the perfectly matched layer (PML) concept as applied to the problem of mesh truncation in the finite-element method (FEM), We show that it is possible to extend the Cartesian PML concepts involving half-spaces to cylindrical and spherical geometries appropriate for closed boundaries in two and three dimensions by defining lossy anisotropic layers in the relevant coordinate systems, By using the method of separation of variables,...
Finite element analysis of fretting contact for nonhomogenous materials Korkmaz, Y. M.; Çöker, Demirkan (2017-09-15) Fretting problem arises in the case of relatively small sliding motion between contacting surfaces. Fatigue life of the components that are in contact with each other, especially in rotorcraft may be significantly reduced due to fretting. The purpose of this study is to investigate material inhomogeneity near the contact region on the fretting problem in a cylindrical on flat contact configuration. A finite element (FE) model was constructed by using commercial finite element package ABAQUS (TM) to study pa...
Use of the reciprocal problems in electro-magnetic source imaging of the human brain Gençer, Nevzat Güneri (2003-09-21) In this work, solution of the Electro-magnetic source imaging forward problem is formulated using the reciprocity theorem. Lead field solutions for electrode potentials and sensor magnetic fields are computed for a realistic head model using the Finite Element Method. Potentials and magnetic fields obtained using the lead fields are compared to analytical solutions and direct numerical solutions. It is found that the accuracy of lead field based solution is comparable to the accuracy of direct numerical sol...
Analysis of variance and linear contrasts in experimental design with generalized secant hyperbolic distribution Yilmaz, Yidiz E.; Akkaya, Ayşen (Elsevier BV, 2008-07-01) We consider one-way classification model in experimental design when the errors have generalized secant hyperbolic distribution. We obtain efficient and robust estimators for block effects by using the modified maximum likelihood estimation (MML) methodology. A test statistic analogous to the normal-theory F statistic is defined to test block effects. We also define a test statistic for testing linear contrasts. It is shown that test statistics based on MML estimators are efficient and robust. The methodolo...
