Abstract: Computer simulation of three-dimensional heat transfer and fluid flow in gas metal arc (GMA) welding has been studied by considering the three driving forces for weld pool convection, that is ...

Abstract: In unshrouded axial turbine stages, a small but generally unavoidable clearance between the blade tips and the stationary outer seal allows a clearance gap leakage flow to be driven across the ...

Abstract: Selected physical properties of asphalt cement are significantly changed by artificial aging under thin film oven test conditions. The changes in physical properties are also reflected in the molecular size distribution ...

Abstract: We study the averaged characteristics of the response of Duffing’s oscillator to harmonic excitation. We show that, as in classical thermodynamics, response characteristics are potential functions ...

Abstract: The presented analytical consideration of tilting-pad bearings incorporates simultaneously the changes in viscosity (due to viscous dissipation) and in the nonambient inlet pressure (due to momentum ...

Abstract: This paper presents a coordinate-invariant differential geometric analysis of manipulability for closed kinematic chains containing active and passive joints. The formulation treats both redundant ...

Abstract: The importance of long-term behavior in integral abutment (IA) bridges has long been recognized. This paper presents an analytical, long-term, response prediction methodology using finite-element (FE) models and compares ...

Abstract: This paper presents a coordinate-invariant differential geometric analysis of kinematic singularities for closed kinematic chains containing both active and passive joints. Using the geometric ...

Abstract: The local heat transfer coefficients are obtained on a rough planar surface simulating in-service turbine stator vane sections. A transient experimental technique is presented that permits the ...

Abstract: Transverse displacement and rotation eigenfunctions for the bending of moderately thick plates are derived for the Mindlin plate theory so as to satisfy exactly the differential equations of ...
