Abstract: From observations of a stream of gas bubbles rising through a liquid, a two-phase mathematical model is proposed for calculating the induced turbulent vertical liquid flow. The bubbles provide ...

Abstract: In many contact problems when friction is not to be neglected the slip phenomenon has not been well understood. The purpose of this paper is to study the slip phenomenon by focusing on a ...

Abstract: In this paper, we have studied the intensification of thermal stresses due to a transverse flow of heat in a fiber of prolate spheroidal shape embedded in an unbounded medium. The analysis ...

Abstract: A simple method is provided for the computation of the redistribution of residual stresses and the stress intensity factors due to the introduction of notches and cracks in a partially ...

Abstract: An oblong elliptic inclusion is perfectly filled in a hole in an infinite plate in the unstressed state. Cavities at the ends of the inclusion will appear as a result of the application of ...

Abstract: A mathematical model of a railroad freight car has been developed under the Track-Train Dynamics Program. The model simulates a car equipped with auxiliary suspension devices (e.g., rubber-cushion ...

Abstract: The present work is on prediction of temperature distribution in noncircular journal bearings and the surrounding solids. Three forms are studied, viz. two-lobe, elliptical and orthogonally displaced ...

Abstract: Most composites are fabricated at elevated temperatures and cooled to room temperature. The difference in coefficients of thermal expansion of the fiber and matrix may cause buckling of the ...
