Research Issues on Punch - Circular Plate Elastic Contacts
(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 ... -
The Influence of Biodiesel Fuels on Lubricity of Passenger Car Diesel Engine Oils
(UDJG, 2010)The present paper mainly focuses on the physical and chemical impact of currently used and future biodiesel components on the performance of a typical low-sulphated-ash-phosphorus-sulphur (low SAPS) passenger car engine ... -
The Neuber’s Rule and a Correlation Between Fretting Fatigue and Plain Fatigue
(UDJG, 2010)Based on these experimental observations and on the remark that any small change on the discontinuity geometry has a significant effect on the stress distribution around it, a stress concentration factor is mandatory to ... -
The Presence of Hydrogen as Wear Environment for the Mechanical System of the Continuous Casting Equipment
(UDJG, 2010)In the last years the continuous casting of the steel has a tremendous development. In the same time, the casting steel quality requirements become higher. The hydrogen as environment of the casting diminishes the steel ... -
Tribological Aspects of Electrode-Elastomer Contact
(UDJG, 2010)Dielectric elastomers (DE) are soft polymers based smart materials that may be potentially employed in applications such as actuation, sensing and energy harvesting. The performance of dielectric elastomer actuators (DEA) ... -
Upon Fretting Behaviour in a Hertzian Point Contact
(UDJG, 2010)Fretting is known as a wear process occurring in a small amplitude cyclic motion of two solid contacting surfaces and it can affect the fatigue resistance of the material, inducing wear and cracking. The kinematics ...
