Abstract: The friction and wear micromechanisms of amorphous hydrogenated carbon films were investigated experimentally using commercially available thin-film rigid disks with sputtered carbon overcoats and ...

Abstract: An experimental investigation of the surface topography, nanoindentation hardness, and nanowear characteristics of carbon thin films was conducted using atomic force and point contact microscopy. ...

Abstract: A small interelectrode gap in Electrochemical Machining (ECM) results in improved dimensional accuracy control and simplified tool design. However, using a small gap with conventional ECM equipment ...

Abstract: The main advantages of the electrochemical machining (ECM) process, such as high material removal rates and smooth, damage-free machined surface, are often offset by the poor dimensional control ...

Abstract: Active pressure for axisymmetric problem under general conditions is formulated and solved by an iterative finite difference solution of the characteristic equations in the present paper. A general lateral stress coefficient ...

Abstract: The writers have come across a difficult stability analysis problem where there are several “strong” local minima. Several well known heuristic global minimum methods fail to locate the global minimum for this case, and ...

Abstract: The current method of steel bar soil nail construction is both labor intensive as well as expensive and many engineers are considering the use of new soil nail materials. In the present pilot test, an innovative soil nail ...
