Experimental Determination of Contact Area Between a Sphere and a Circular Plate Using a Technique Based on Laser Profilometry

Trandafir, Marius; Ciornei, Maria; Diaconescu, Emanuel (UDJG, 2011)

This paper presents the experimental determination of contact area between a steel sphere and a sapphire circular plate, using a technique based on laser profilometry. The reflectivity value is smaller inside contact area ...
Experimental Preliminary Research Regarding Normally and Tangentially Loaded Contacts

Ciornei, Maria; Trandafir, Marius; Diaconescu, Emanuel (UDJG, 2011)

The purpose of this paper is to determine the contact area for a contact between a steel sphere and a sapphire disk loaded normally and tangentially, using laser profilometry. For this, was used an experimental device ...
A Simple Device for Modelling Bioarticular Joint Friction

Bejinariu, Brîndusa; Diaconescu, Emanuel (UDJG, 2011)

In this paper a simple device for modelling bioarticular friction is presented. The experimental device serves to simulate the movement as it would take place in a knee joint. Key components of the experimental device are ...
