Experimental investigation of porous metal bearings
(Inegi-Inst Engenharia Mecanica E Gestao Industrial, Porto, 2012)
Self lubricated sliding bearings production and investigations are still in great expansion because of their very practical maintenance and very long operating life. This is probably the main reason for their common use ...
Microstructural changes of Nimonic-263 superalloy caused by laser beam action
(IOP Publishing Ltd, Bristol, 2012)
Pulsed laser treatments induce changes in the microstructure of materials. We have exposed the Nimonic-263 superalloy to pulsed laser beams of various repetition rates and wavelengths and investigated the changes in ...
High reflectance as desired property of shining surface and undesired for laser welding in jewel production of 585 gold alloy
(Metalurgia International, 2013)
For most of golden jewels the desired property is the shining surface. From the other point of view, high level of shining leads to great reflectance of impinged beams from a surface. It means that when a laser beam is ...
Process of generating of quality solution of the oil gear pump which is leading to effectively high performance product
(Technics Technologies Education Management, 2012)
The paper is presented the basis of a procedural character of the generating of new products like hydraulic units with high quality and performance. The oil gear pump is present in various hydraulic systems that can be ...

Failure analysis of hydraulic turbine shaft
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
This paper describes the analysis of major failure of 28 MW horizontal hydro turbine shaft. The analysis of load carrying capacity of critical radius and fractography analysis are presented. Special emphasize is on ...
Development and application of crack parameters
(Springer, Dordrecht, 2009)
The development, definition and implementation of crack parameters (stress intensity factor, crack tip open displacement, J integral, filial stretch zone) are presented. They are now used for structural integrity and ...
The Geometry Influence on Integrity Thresholds for a Cracked Cylinder
(wiley, 2010)
By applying the EPRI engineering approach, threshold values of pressure for internally pressurized axially cracked long cylinder are calculated. The JR curve and the crack driving force J are approximated by polynomials ...
Improvement of algorithm for numerical crack modelling
(Springernature, London, 2010)
For numerical simulation of crack modelling in fracture mechanics the eXtended finite element method (Xfem) has been recently accepted as a new powerful and efficiency methodology. In the paper we present the details of ...
