ON THE INFLUENCE OF DENSITY ON THE WAVE PROPAGATION IN FLUIDS
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2012, Vol 57, Issue 1
Abstract
In this paper we investigate the influence of the density on the propagation of waves in fluids with exponential and cosine stratification, respectively. We show that the waves are pairs of solitons, each pair consisting of two opposite directions propagating waves of the same mode. The modes of the two pairs are different from each other, and are different from the m-th and n-th modes. The original waves propagate after interaction without changing their identities, but only the m-wave suffers a shift of phase.

ON MODELING THE MECHANICAL BEHAVIOR AND TEXTURE EVOLUTION OF ROLLED AZ31 MG FOR COMPLEX LOADINGS INVOLVING STRAIN PATH CHANGES
An accurate description of the deformation response of AZ31 Mg under changing strain paths requires consideration of its strong anisotropy and its evolution with accumulated plastic deformation. In this paper, the viscop...
NUMERICAL SIMULATIONS OF NAKAZIMA FORMABILITY TESTS WITH PREDICTION OF FAILURE
This paper presents results of numerical simulations of the Nakazima test with determination of formability without using the forming limit curve. The onset of localized necking has been determined using the criterion ba...

GAS TURBINE AS RANGE EXTENDER FOR FUTURE ELECTRIC AUTOMOBILES
The propulsion of automobiles by motors, especially by hub motors, integrated into the wheels, offers remarkable advantages in terms of vehicle dynamics, stability and freedom of movement. But the most important benefit...
TRAJECTORY PLANNING OF A PENDULUM-DRIVEN UNDERACTUATED CAR
The control problem of the pendulum-driven cart has been well studied in several literatures. The challenge issue of control of such underactuated systems is to control the motions of the pendulum and the cart by applyin...
