Although it is noted in the literature that the presence of a central hole in an elastic layer bonded to rigid surfaces can cause significant drop in its compression modulus not much, attention is given for investigating thoroughly and in detail the influence of the hole oil the layer behavior. This paper presents analytical solutions to the problem ofthe uniform compression of bonded hollow circular elastic layers, which includes solid circular layers as a special case as the radius of hollow section vanishes. The closed-form expressions derived in this study are advanced in the sense that three of the commonly used assumptions in the analysis of bonded elastic layers are eliminated: (i) the incompressibility assumption, (ii) the "pressure" assumption and (iii) the assumption that plane sections remain plarreafter deformation. Through the use of the analytical solutions derived in the study, the compressive behavior of bonded circular discs is studied. Particular emphasis is given to the investigation of the effects of the existence of a central hole on the compression modulus, stress distributions and maximum stresses/s trains in view of three key parameters: radius ratio of the hole, aspect ratio of the disc and Poisson's ratio of the disc material.

Inter-granular cracking through strain gradient crystal plasticity and cohesive zone modeling approaches Yalçınkaya, Tuncay; Fırat, Arzu (Elsevier BV, 2019-10-01) Even though intergranular fracture is generally regarded as a macroscopically brittle mechanism, there are various cases where the fracture occurs at the grain boundaries with considerable plastic deformation at the macroscopic scale. There exists several microstructural reasons for grain boundaries to host crack initiation. They can interact with impurities and defects, can provide preferential location for precipitation, can behave as a source of dislocations and can impede the movement of dislocations as...
Separation at the interface of non-linearly elastic spinning tube-rigid shaft subjected to circumferential shear Akyüz, Uğurhan (Elsevier BV, 2004-10-01) Separation at the interface of homogeneous, isotropic, compressible, hyperelastic, spinning cylindrical tube-rigid shaft subjected to circumferential shear is investigated within the context of the finite elasticity theory. The compressible, hyperelastic spinning tube with a uniform wall thickness is assumed to be tautly fitted to a rigid shaft along its inner curved surface. The outer surface of the tube is subjected to a constant uniformly distributed circumferential shearing stress while the rigid shaft ...
Elastic layers bonded to flexible reinforcements Pinarbasi, Seval; Mengi, Yalcin (Elsevier BV, 2008-02-01) Elastic layers bonded to reinforcing sheets are widely used in many engineering applications. While in most of the earlier applications, these layers are reinforced using steel plates, recent studies propose to replace "rigid" steel reinforcement with "flexible" fiber reinforcement to reduce both the cost and weight of the units/systems. In this study, a new formulation is presented for the analysis of elastic layers bonded to flexible reinforcements under (i) uniform compression, (ii) pure bending and (iii...
Solution of the dynamic frictional contact problem between a functionally graded coating and a moving cylindrical punch BALCI, MEHMET NURULLAH; Dağ, Serkan (Elsevier BV, 2019-04-01) This paper presents an analytical method developed to investigate the dynamic frictional contact mechanics between a functionally graded coating and a rigid moving cylindrical punch. Governing partial differential equations of elastodynamics are solved analytically by applying Galilean and Fourier transformations. Interface continuity and boundary conditions are written and contact problem is then reduced to a singular integral equation of the second kind. The singular integral equation is solved numericall...
Investigation of the variations in microstructure and mechanical properties of dual-matrix ductile iron by Magnetic Barkhausen Noise analysis Gür, Cemil Hakan; Erdogan, Mehmet (Informa UK Limited, 2008-01-01) The variations in the microstructure and tensile properties of dual-matrix ductile irons have been investigated non-destructively by Magnetic Barkhausen Noise (MBN) method. Specimens have been intercritically austenitised at 795 degrees C and 815 degrees C for 20 minutes, and then oil-quenched to obtain different martensite volume fractions. Two specimens, namely as-cast and oil-quenched from 900 degrees C, were prepared for comparison purpose. To investigate the effect of tempering, some specimens were tem...
