Abstract: This chapter deals with a hydrodynamic journal bearing provided with hollow bushings, capable of supporting very high loads, even at low speeds, at which separation between the shaft and the ...

Abstract: Permanent magnet pairs have negligible friction; however, the levitating member is unstable. In this paper, it is demonstrated that if the other member vibrates in a suitable way, the levitating ...

Abstract: The new principle of flow self-regulation is applied to hydrostatic screws and nuts. These self-regulating hydrostatic screws and nuts permit a continuous and automatic distribution of the total ...

Abstract: At high stress levels the creep strain rate for many materials varies as the exponential of stress while at low stresses it varies as stress to some power. An analysis is presented for a ...

Abstract: Recent works have demonstrated that construction and demolition waste (CDW) aggregates for subbase road pavement applications can be stabilized via the alkali activation of their fine fraction (d<0.125  mm). Despite the ...

Abstract: This paper focuses on aspects of fracture mechanics of interface cracks in anisotropic bimaterials. In this case there is a coupling of all three crack-tip fracture modes in the natural ...

Abstract: A cohesive zone model of the Dugdale-Barenblatt type is used to investigate crack growth under small-scale-creep/damage conditions. The material inside the cohesive zone is described by a power-law ...

Abstract: Surveys on innovative materials for aircraft arrestor beds are of great interest in airport safety research. In the event of a runway overrun, the arrestor bed has to provide for the complete stop of the aircraft. In doing ...
