In this paper, we investigate the combined effect of viscous damping and Coulomb friction on sampled-data mechanical systems. In these systems, instability can occur due the sampling of the applied discrete-time controller which is compensated by the two ... see more

This paper investigates the stability of a digitally controlled pendulum with Coulomb friction as primary source of dissipation. We focus on the stabilizing effect of friction against vibrations due to the otherwise unstable parameter settings, and we sho... see more

In the present study, an influence of friction welding parameters on the mechanical properties of dissimilar steel materials of AISI D3 tool steel and AISI 304 stainless steel joints. The welding conditions were optimized with the effect of various weldin... see more

A generalised form of Reynolds equation for two symmetrical surfaces is derived considering velocity-slip at the bearing surfaces. This equation is applied to study the effects ofvelocity -slip for the lubrication of roller bearings under lightly loaded c... see more

This study examines the problem of an MHD free convection flow in the presence of a temperaturedependent heat source in a viscous incompressible fluid between a long vertical wavy wall and a parallel flat wall with constant heatflux and slip flow boundary... see more

Optimization of the process was still the issue in manufacturing. Investigation on the process parameters that effects to the property of welded structure were necessary. In this study, the AA5052-H32 sheets of 2 mm thick were welded using friction stir s... see more

Properties like light weight, high strength-to-weight ratio, and good corrosion resistance make aluminium alloys widely accepted in automotive industry. The low melting point of these alloys makes welding by traditional methods difficult due to the impe... see more

Dynamic friction coefficients of agricultural crops are applied in designing silos, agricultural crops storage structures, transporting, handling machines and discharging implements.  In this study, at first an apparatus for measuring dynamic frictio... see more

To design the planting, separating, threshing, sizing and packing machines for agricultural products, physical and mechanical properties of the products should be known. In this paper, some physical properties of red radish seeds were studied. Dimensional... see more
