Abstract: Fretting-wear and fretting-fatigue loadings can both result in wear (material loss) and in crack nucleation and propagation (fatigue process). This paper deals with cracking induced by small ...

Abstract: This paper concerns an experimental investigation of fretting behavior using grease lubrication for ball (ball bearing steel) -flat (low alloyed steel) contact. The influences of the imposed ...

Abstract: The object is construction of a thermohydrodynamic theory of thrust bearings. The bearing pad has the geometry of an annular sector and is supported in one point; about this point it is free ...

Abstract: This is Part II, of a three-part sequence of papers on pivoted thrust pads. In this paper we apply the thermohydrodynamic theory of Part I to statically loaded, sector shaped pivoted thrust ...

Abstract: In a semi-free field, the acoustic field is composed of two components: the direct sound and the reflected sound. Because it is difficult to separate the direct sound from the acoustic field, ...

Abstract: This paper investigates the behavior of simply supported prestressed steel–concrete composite beams through experimental and analytical studies. Eight specimens were instrumented and tested in the experimental program ...

Abstract: Increasingly, military and civilian applications of electronics require extremely high-heat fluxes on the order of 1000 W/cm2. Thermal management solutions for these severe operating conditions are ...
