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 partial sliding and stress concentrations. In order to investigate the effect of material inhomogeneity, the fretting contact is analyzed by introducing voids near the contact region. The void size and an array of voids is introduced into the substrate. The results are compared in terms of pressure, shear traction, tangential stress magnitudes and relative slip between the contacting materials.

Finite element analysis of fretting contact for dissimilar and nonhomogeneous materials
Korkmaz, Yezdan M.; Çöker, Demirkan (Elsevier BV; 2017-09-07)
Fretting problem arises in the case of relatively small sliding motion between contacting surfaces leading to reduction in fatigue life of these parts significantly. The purpose of this study is to investigate the effects of fretting on the contact region in a cylindrical on flat contact configuration. In order to identify fretting contact, a finite element (FE) model was constructed by using commercial finite element package ABAQUS (TM). Fretting contact is studied under two types of loading: tangential lo...
MODELING OF CONTROL FORCES FOR KINEMATICAL CONSTRAINTS IN MULTIBODY SYSTEMS DYNAMICS - A NEW APPROACH
IDER, SK (Elsevier BV, 1991-01-01)
Conventionally kinematical constrains in multibody systems are treated similar to geometrical constraints and are modeled by constraint reaction forces which are perpendicular to constraint surfaces. However, in reality, one may want to achieve the desired kinematical conditions by control forces having different directions in relation to the constraint surfaces. In this paper the conventional equations of motion for multibody systems, subject to kinematical constraints, are generalized by introducing gener...
Moving contact problems involving a rigid punch and a functionally graded coating
Balci, Mehmet N.; Dağ, Serkan (Elsevier BV, 2020-05-01)
Frictional contact mechanics analysis for a rigid moving punch of an arbitrary profile and a functionally graded coating/homogeneous substrate system is carried out. The rigid punch slides over the coating at a constant subsonic speed. Smooth variation of the shear modulus of the graded coating is defined by an exponential function and the variation of the Poisson's ratio is assumed negligible. Coulomb's friction law is adopted. Hence, tangential force is proportional to the normal applied force through the...
Analysis of frictional contacts with heat generation considering temperature dependent properties
BALCI, MEHMET NURULLAH; YILDIRIM, BORA; Dağ, Serkan (2015-10-01)
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...
MHD Stokes flow in lid-driven cavity and backward-facing step channel
Gurbuz, Merve; Tezer, Münevver (River Publishers, 2015-01-01)
The 2D Magnetohydrodynamics Stokes flow equations are solved in a lid-driven cavity and backward-facing step channel in the presence of a uniform magnetic field with different orientations. The hydrodynamic and electromagnetic equations are solved simultaneously using Stokes approximation in terms of velocity, pressure, stream function and vorticity with an iterative procedure. The radial basis function approximations are used to terms other than diffusion satisfying the boundary conditions at the same time...
