Influence of Atmospheric Conditions on the Mechanical Properties of Pet Rubber Composites
(Universitatea "Dunărea de Jos" din Galați, 2005)
The aim of paper is to study the influence of environmental open air conditions
on the PET-rubber composites. Two set of samples (Type I, Type II) were obtained
with the same composition, but the composites of Type I are ...

added material was a bronze with aluminum complex alloyed with ...
Laser Surface Hardening of 51Crv4 Steel
(Universitatea "Dunărea de Jos" din Galați, 2005)
The work presents the surface changes in microstructure and properties by
quenching the 51CrV4 steel from liquid and solid phase, using a CO2 continue laser
wave with 900W power. In order to determine the hardening ...
Study on the Soil chemical Pollution in the Area of the Residual Bauxite Lake "Mineri"-Tulcea
(Universitatea "Dunărea de Jos" din Galați, 2017)
The paper presents a study on the impact of chemical pollution of the soil,
from residual bauxite lake, from "Mineri", in the areal of Tulcea. Soil samples were
taken from the lake, and from the immediate area of the ...
Assessment of the Influence of Breakage Strenth Rocks by Cox Method
(Universitatea "Dunărea de Jos" din Galați, 2016)
Analyzed according to the theory of continuous mechanics, medium rock
massif is a natural environment difficult to know, so the forecasts referring to its
behaviour are approximate and uncertain. Such an assertion becomes ...
Static and Dynamic Analysis of Stress and Deformations of Răstolița Dam
(Universitatea "Dunărea de Jos" din Galați, 2016)
Large Dams are a particularly important case of seismic risk assessment. On
the one hand, the dams themselves have a high value, having implications for the
whole economy, through the production of electricity, water ...
The Dynamic Simulation for a Cold Rolling Mill Machine
(Universitatea "Dunărea de Jos" din Galați, 2016)
For a cold rolling mill machine that represents a mechanical system, the
dynamics problems may be solved by using the differential equations of their
movement. We must consider all the connections and couplings for the ...
