Fatigue Sensitivity Analysis of a Ship Structural Detail
(Universitatea ”Dunărea de Jos” din Galați, 2009)
In the paper, a FEM analysis used for fatigue assessment, based on the rules, was done. The approach for fatigue assessment in the early design stage of the ship structure has been developed. To overcome the challenges due ...
Rapeseed Oil Flammability on Hot Surface
(Universitatea ”Dunărea de Jos” din Galați, 2009)
The paper presents the tests and results upon rapeseed oil flammability on hot surface. The oil samples were obtained from a rapeseed oil after a dewaxing process. There were established temperature ranges for which the ...
Fabric Reinforced Filled 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, ...
Measuring the Residual Stress of the Injection Moulded Polymeric Parts
(Universitatea ”Dunărea de Jos” din Galați, 2009)
The residual stresses are usually introduced during manufacturing, and are caused by processes such as molding. This paper presents how the authors determine the residual stresses for the flat plates from ABS, PP and PS ...
Torsional Analysis of Ship Hull Model
(Universitatea ”Dunărea de Jos” din Galați, 2009)
In this paper a new methodology (numerical and experimental) proposed to analyze the ship hull torsion is treated. The torsion analysis is performed on a scale model (1:50) of a container ship, made of composite material. ...
Clay/Epoxy Composites
(Universitatea ”Dunărea de Jos” din Galați, 2009)
Fillers are generally used to decrease the costs of a composite material but they are changing also some of composite’s properties due to their physical properties, their dimensions and their shapes. Filled polymer could ...
Preliminary Results on the use of Palm Oil and Shea Butter in Lubrication Process in Food Industry
(Universitatea ”Dunărea de Jos” din Galați, 2009)
In this study, vegetal oils (palm oil and shea butter) are analyzed for their uses in lubrication of mechanical part of machines in food industry. These vegetal oils were analyzed by X-ray diffraction and transmission ...
Structure Assessment by X-Ray Difractometry for Ceramic Materials used in Oral Prosthetic Systems
(Universitatea ”Dunărea de Jos” din Galați, 2009)
The paper presents a difractometric analysis on two types of ceramics nowadays available on the market and frequently used in restorative dentistry: InLine (IVOCLAR) and Hera-Ceram (HAEREUS KULZER). The diffractograms ...
A Fast Numerical Method to Predict Elastic Fields Due to Eigenstrains in an Isotropic Half-Space PartII. Program Validation and Simulations
(Universitatea ”Dunărea de Jos” din Galați, 2009)
A fast algorithm to solve the inclusion problem for arbitrarily shaped eigenstrains is validated in this paper. Influence coefficients formulas and numerical predictions for elastic fields due to a spherical region of ...
