Abstract: Experiments on the sliding of boron carbide on boron carbide in atmospheres of dry air and water vapor at room temperature have shown the frictional behavior of boron carbide to be similar ...

Abstract: Three modes of tap failure have been considered: too high a cutting force, jamming of the swarf in worn corners of the cutting edges, and loss of thread form. In tests in which a high ...

Abstract: The mechanics of cords is analyzed under simple bending to understand the fatigue failure mechanism of synchronous belts. A simplified beam model of synchronous belt bending is then proposed ...
