Analysis of Surface Roughness and Micro-hardness in Roller Burnishing of Aluminum Alloy 6061
Burnishing is a chip-less finishing process, in which a hard roller or ball presses the surface layer of part to perform plastic deformation in the surface layer and produce improved finish, enhanced hardness and compressive residual stresses on the surface of special materials such as Aluminum and Brass. In the following research, the effect of input parameters such as feed rate, cutting speed...

Earthquake Analysis of 3-D Structures on Sliding Foundation Using Yield Equation of the Contact Surface
A solution technique for the dynamic analysis of asymmetric base-isolated buildings, subject to earthquake ground motion, is presented. To develop the formulation, a yield surface as a function of both shear force and torsion moment of the sliding surface with rigid perfectly plastic behavior is constituted. To achieve the objective, the yield stress is defined by the friction coefficient throu...

متن کاملTubing failure during prolonged roller pump use: a laboratory study.
Little is known about the mechanical forces acting on extracorporeal circuit tubing with prolonged roller pump use during extracorporeal membrane oxygenation (ECMO). We examined the time to tubing rupture of three different materials during actual roller pump use, mean and standard deviation (SD) (SD shown in parentheses): Tygon (control) 243.7 h (175.4); LVA 121 h (14.3); and SRT 6.6 h (2.1). ...
