Abstract: This study investigates dynamic instability in a high-speed drilling process. A pretwisted beam is used to simulate the drill. The time-dependent nature of the thrust force and the drilling ...

Abstract: This paper investigates the tip characteristics of an oblique crack in the wheel-rail contact problem. The wheel-rail normal contact pressure and interfacial shear stress distributions, and the ...

Abstract: This study employs an elastic-plastic finite element model to investigate the effect of oblique rail surface crack on the wheel-rail contact stress distribution under partial slip rolling conditions. ...

Abstract: In this study, the authors have conducted a series of numerical experiments to investigate the flow circulations in the Central Valley of California and the formation mechanisms of the Fresno eddy. The authors have found ...

Abstract: The stability of a footing may be destabilized near a retaining wall because of increased lateral displacement and decreased soil confining pressure. The stability of footing within this footing–soil–wall system is complex ...

Abstract: The growing demand for highly skilled graduates coupled with institutional mandates to reduce minimum graduation credit hour requirements is compelling higher educators to optimize the deployment strategy of high-impact ...

Abstract: A lubrication theory that includes the coupled effects of surface roughness and anisotropic slips is proposed. The anisotropicslip phenomena originate from the microscale roughness at the atomic scale (microtexture) and ...

Abstract: By coupling the equations of the modified Reynolds equation with the anisotropic slip effect, the piezoviscosity and piezodensity relations, the elasticity deformation equation, and the load equilibrium equation are solved ...

Abstract: Dynamic equations of the intermittent-motion of a globoidal cam driven system were derived in this study. The effects of roller mesh flexibility and cam profile curve on the residual vibration ...

Abstract: Sedimentation in a drain system has been recognized as one of the major causes of nuisance flooding produced by localized storms in Southeast Texas. The objective of the study is to assess the sediment load from runoff ...
