An Analytical Procedure to Incorporate the Bauchinger Effect on Fretting Fatigue Models
(Universitatea ”Dunărea de Jos” din Galați, 2009)
This paper proposes a modification on SWT model concerning the prediction on fretting fatigue life, in order to take into account the material deviation from the ideal elastic-plastic behaviour, the so-called “Bauschinger ...
Characterisation of Particulate Epoxy Composites
(Universitatea ”Dunărea de Jos” din Galați, 2009)
Among composites, the polymer matrix ones are the cheapest and the easiest to form but they show major disadvantages such as poor electrical and thermal conductivity, low fire resistance etc. In the case of any composite, ...
On the Effect of Spectral Characteristics of Roughness on Contact Pressure Distribution
(Universitatea ”Dunărea de Jos” din Galați, 2009)
In the first part of the paper, the matrix containing the roughness heights is obtained by a linear transformation of the Gaussian input matrix, the coefficients of the transformation matrix being found as solutions of a ...
A Numerical Solver for the Wheel-Rail Contact Subjected to Combined Loads
(Universitatea ”Dunărea de Jos” din Galați, 2009)
A working algorithm, able to be incorporated into a computer code, has been developed to solve the stress state in the general case of non-Hertzian contacts. Brent’s method has been involved to find the contact point for ...
Damage Prediction in Fatigue Corrosion Processes
(Universitatea ”Dunărea de Jos” din Galați, 2009)
The paper aims to establish an algorithm for determining the values and evolution of the stress concentration factor in corrosive environment, and establish its influence on the fatigue strength of steel required in a ...
Experimental Study of Friction Losses in Ball Screws
(Universitatea ”Dunărea de Jos” din Galați, 2009)
In contrast with conventional sliding lead screws, ball screws with rolling friction between the screw and nut have high efficiency, accurate positioning and smooth, quiet operation at low friction that make this kind of ...
