An Analytical Procedure for the Prediction of the Stress-Strain State in Notches Under Multiaxial Fatigue
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
This work presents an analytical procedure for estimating elastic-plastic
stresses and strains in notched shafts subjected to synchronous non-proportional
torsional and tensile cyclic loading. The specification of the ...
Thermal Analysis of Inoculated Grey Cast Irons
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
A research was done to investigate the effect of 0.05…0.25wt.% addition
rate of Ca, Zr ,Al – FeSi alloy, in ladle and in-mould inoculation of grey cast
irons. In the present paper, the conclusions drawn are based on ...
Structural Characteristics in Cobalt Based Alloys
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
In the present paper there are presented results of investigations on samples of
partially removable denture made of cobalt base alloys (Co-Cr-Mo) regarding

Contribution in the Domain of the Contact Stresses Between Cylinders of Cold Rolling
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
Elasto-plastic contact stresses between working cylinder and support cylinder of
cold rolling using FEM are presented in this paper. Pressure and tractions resulted
from the rolling process were obtained by using a ...
On the Constitutive Equation of a Low Carbon Steel
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
The paper shows the results of the researches concerning the equation of
deformation behavior of low carbon steel. The behavior law is established starting
from the experimental torsion moment. The composed constitutive ...

(Universitatea "Dunărea de Jos" din Galați, 2008)
Within the frame of this work, the technical procedures and real advantages of
using Glow Discharge Optical Emission Spectroscopy (GDOES) for establishing
depth concentration profiles of surfaces are presented. GDOES can ...
Steel and Refractory Chemical Interactions and Mechanical Behavior of Plates for Sliding Gate During Steel Continuous Casting
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
The main objective to increase CC productivity as well as steel quality by using
optimized refractory from ladle-tundish-to-mold lead to techniques that allow the
prediction of steel and refractory chemical interactions ...
X-Ray Diffraction Study of the Rewverse Martensitic Transformation in Cu-Al-Ni Shape Memory Alloy
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
The paper presents an X ray diffraction study for a cooper based shape memory
alloy. The behavior of CuAl13Ni4 alloy, which exhibits a peculiar property, is
evaluated by structural changes. On cooling, the martensitic ...
