Characteristics of Material in Zone of Cut by Laser Cutting
(UDJG, 2010)
The laser cutting is a cost effective technology. This process is based on melting and evaporating material in very small, a well-defined area and a blownout of the cut by the assist gas. Laser cutting processes make heat ...
Numerical Modelling of 3D Impact
(UDJG, 2010)
The paper presents a virtual device designed for studying tri-dimensional impact. The main goal of the work is to present a solution for finding the coefficient of restitution for the tri-dimensional case of a sphere ...
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 ...
Multipurpose Ecological Lubricating Greases
(UDJG, 2010)
Lubricants facilitate the effective operation of mechanical equipment, reducing friction and wear, but, in the same time, they are a large and diffuse pollution source, both on soil and in water. Eliminating or reducing ...
