RISInfluence of Surface Roughness Lay Directionality on Scuffing Failure of Lubricated Point Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influence of roughness lay directionality on scuffing failure is studied considering different roughness lay direction combinations of the contacting surfaces of a ballondisk contact. Using a recently developed scuffing ...
On Global Energy Release Rate of a Permeable Crack in a Piezoelectric Ceramic
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A permeable crack model is proposed to analyze crack growth in a piezoelectric ceramic. In this model, a permeable crack is modeled as a vanishing thin, finite dimension, rectangular slit with dielectric medium inside. A ...
The Effects of Microdimple Texture on the Friction and Thermal Behavior of a Point Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study investigates the effects of the microdimple texture on the friction and surface temperature performances of a ball-on-disk contact, operating under the speed and load ranges that cover typical gearing applications. ...
A New Multi-Objective Genetic Algorithm for Assembly Line Balancing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The aim of this work is to enable a step towards a self-adapting digital toolset for manufacturing planning focusing on minimally constrained assembly line balancing. The approach includes the simultaneous definition of ...
An Investigation of the Impacts of Contact Parameters on Wear Coefficient
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, the wear depths under different loads, speeds, lubricant temperatures, and surface roughness amplitudes are experimentally determined using a twindisk rolling contact setup. A point contact wear model combining ...
Prediction of Mechanical Power Loss of Planet Gear Roller Bearings Under Combined Radial and Moment Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A modeling methodology is proposed to predict loaddependent (mechanical) power loss of cylindrical roller bearings under combined radial and moment loading with focus on planetary gear set planet bearings. This methodology ...
Understanding Female Students’ Choice of a Construction Management Undergraduate Degree Program: Case Study at an Australian University
Publisher: American Society of Civil Engineers
Abstract: The considerably low female student enrollments in construction management (CM) undergraduate degree programs have continued to draw attention from academia. With a cohort of local and international female students in a ...

Abstract: The aim of this work is to enable a step towards a selfadapting digital toolset for manufacturing planning focusing on minimally constrained assembly line balancing. The approach includes the simultaneous definition of the ...
Experimental Study of Flow Characteristics in Wedge and Modified Wedge Transitions
Publisher: American Society of Civil Engineers
Abstract: Water generally leaves a supply reservoir through a narrow rectangular concrete channel and enters a large trapezoidal earthen channel. The two channels are connected by a transition. Among the most common types of ...
Three Dimensional Numerical Analysis of Turbulent Flow in Porous Media Formed by Periodic Arrays of Cubic, Spherical, or Ellipsoidal Particles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present paper, threedimensional (3D) turbulent flow in the porous media formed by periodic arrays of particles is numerically investigated. 3D Navier–Stokes equations and a standard kخµ turbulence model with ...
