Influence of Additive concentration in Soybean Oil on Rheological and tribological Behavior
Journal Title: INCAS BULLETIN - Year 2018, Vol 10, Issue 4
Abstract
The rheology of vegetal oils, additivated or not and the factors that influence their viscosity have been studied by specialists, in order to introduce these oils as lubricants in green industries as agriculture, food processing, transportation and for complying with environmental and health regulations; the vegetal oils are also envisaged as an eco-friendly alternative to similar mineral and synthetic products. This study presents the influence of nature and concentration of additive in soybean oil on its rheological and tribological behavior, reflected by shear stress - shear rate, viscosity - temperature curves and by the wear scar diameter (WSD) after testing the formulated lubricants on a four- ball machine.

A Numerical Solution for the Lifting Surface Integral Equation
In this paper, we present a new numerical treatment of the lifting surface integral equation (LSIE) in the case of rectangular wing planform. The kernel of this equation possesses a strong singularity in Hadamard sense....
Comparative study between 2D and 3D FEM techniques in single bolt, single lap, composite bolted joints for space structures
Two-dimensional and three-dimensional finite element models have been developed to study the effects of bolt-hole clearance on the mechanical behavior of bolted composites (graphite/epoxy) joints in space structures. The...
