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 ... -
Research Issues on Punch - Circular Plate Elastic Contacts
Trandafir, Marius; Diaconescu, Emanuel (UDJG, 2010)Circular plates enter into the category of finite dimension bodies. Solutions regarding the displacements and stresses, which appear at the contact involving finite dimension bodies and also numerical and analytical results ...
