Abstract: This paper describes experimental results from a research program aimed at a study of the static and dynamic characteristics of liquid long annular seals. A seal test rig permits the identification ...

Abstract: Friction and adhesion coefficients of copper on copper were measured in vacuum (5 × 10−10 to 4 × 10−7 torr) at temperatures ranging from −270 to 1000 F, and in controlled pressures ...

Abstract: It may be necessary to provide a radial opening such as gas evacuator holes, or an opening to operate the unlocking of the bolt mechanism by means of exhaust gases, in a gun barrel, which ...

Abstract: A multi-linear kinematic, two dimensional finite element model incorporating Bauschinger effect, developed using ANSYS commercial software is used to determine the effect of machining both at the ...

Abstract: In this review the developments in the fields of lubricants, friction, and bearing materials have been summarized by various authorities in each particular field. The review covers the period ...
