A variable friction model that relates the parameters of sheet metal drawing to the local lubrication conditions taking place during the deformation, has been integrated to a finite element program. Variable friction coefficients for the contacting surfaces are determined from the friction model, which uses the related parameters obtained at each time step of the finite element program as inputs. A number of numerical runs have been performed and the strains are compared with the experimental results for circular blanks. A good agreement is obtained between the numerical and experimental results for the variable friction model used.

Effect of differential lubrication on the cup drawing of mild steel blanks Atala, H. (Elsevier BV, 1990-7) Cup-drawing test have been performed on mild steel blanks to study the frictional behaviour of the flanges in a cup-drawing operation, by utilizing differential lubrication. Molybdenum disulphide paste has been chosen as the lubricant because of its good performance in preliminary trials. The results suggest that lubrication of the flange is essential in the achievement of a fully drawn cup without failure and without wrinkles. It can also be stated that lubricant application to central regions appears to b...
A MODEL OF PISTON SECONDARY MOTION AND ELASTOHYDRODYNAMIC SKIRT LUBRICATION Dursunkaya, Zafer; GANAPATHY, V (ASME International, 1994-10-01) A model of elastohydrodynamic lubrication of piston skirts in reciprocating engines was developed in the context of a simulation of piston secondary motions. The piston secondary dynamics, skirt lubrication and skirt elastic deformation problems are simultaneously solved in the calculation. The model can represent both conventional and two-piece articulated pistons and also includes a treatment of wristpin lubrication. Skirt deformations are calculated using a skirt compliance matrix derived from a finite e...
Dynamic frictional contact problems involving elastic coatings BALCI, MEHMET NURULLAH; Dağ, Serkan (Elsevier BV, 2018-08-01) This paper presents a general theory of dynamic frictional contact of elastic coatings pressed against by a rigid punch moving with a constant speed. Governing equations of elastodynamics are solved by applying Galilean and Fourier transformations. The contact problem is then reduced to a singular integral equation, which is solved numerically. Developed procedures are verified through comparisons made to the available computational and analytical results. Parametric analyses illustrate the influences of pu...
Effect of cyclic thermal loading on the performance of steel H-piles in integral bridges with stub-abutments Dicleli, Murat (Elsevier BV, 2004-02-01) In this paper, analytical equations are developed to estimate the lateral displacement capacity of steel-H piles in integral bridges with stub abutments subjected to cyclic thermal variations. First, steel H piles that are capable of sustaining large plastic deformations are identified based on their local buckling strength. The normalized moment-curvature relationships of these piles are then obtained for various axial load levels. Next, a low-cycle fatigue damage model is employed to determine the maximum...
Effect of surface roughness in microchannels on heat transfer Turgay, Metin Bilgehan; Güvenç Yazıcıoğlu, Almıla; Department of Mechanical Engineering (2008) In this study, effect of surface roughness on convective heat transfer and fluid flow in two dimensional parallel plate microchannels is analyzed by numerically. For this purpose, single-phase, developing, laminar fluid flow at steady state and in the slip flow regime is considered. The continuity, momentum, and energy equations for Newtonian fluids are solved numerically for constant wall temperature boundary condition. Slip velocity and temperature jump at wall boundaries are imposed to observe the rarefa...
