Considering bearing curves of roughness on face milled surfaces of steel
Petropoulos, G.; Pandazaras, C.; Stamos, I. (2001)The present contribution describes the statistical analysis of bearing (Abbott) curves of surface roughness produced by face milling of steel. Bearing curves parameters are found to closely correlate with feed rate and ... -
Evaluating the real profile length in turning of carbon steels
Petropoulos, G.; Pandazaras, C. (2003)The real profile length constitutes a hybrid parameter in surface metrology which is rather neglected in literature, albeit it affects or controls sometimes surface functional properties like corrosion resistance, adhesibility, ... -
A feasibility study of dynamic stress analysis inside a running internal combustion engine using synchrotron X-ray beams
Baimpas, N.; Drakopoulos, M.; Connolley, T.; Song, X.; Pandazaras, C.; Korsunsky, A. M. (2013)The present investigation establishes the feasibility of using synchrotron-generated X-ray beams for time-resolved in situ imaging and diffraction of the interior components of an internal combustion engine during its ... -

Influence of local soil conditions on mouldboard ploughshare abrasive wear
Natsis, A.; Petropoulos, G.; Pandazaras, C. (2008)A major problem related to use of tillage equipment is ploughshare wear due to abrasion by soil hard particles, as it seriously affects tillage quality and agricultural production economy. In the present study it is attempted ... -
Modeling of surface finish in electro-discharge machining based upon statistical multi-parameter analysis
Petropoulos, G.; Vaxevanidis, N. M.; Pandazaras, C. (2004)A multi-parameter analysis of surface finish imparted to Ck60 steel plates by electro-discharge machining (EDM) is presented. The interrelationship between surface texture parameters and process parameters is emphasized. ... -
POSTULATED MODELS FOR THE FRACTAL DIMENSION OF TURNED METAL SURFACES
Petropoulos, G.; Vaxevanidis, N.; Pandazaras, C.; Koutsomichalis, A. (2009)Fractal geometry has been introduced to describe the roughness of machined surfaces for providing evaluation by one or two parameters. The present contribution is aimed at modelling the interactions of cutting conditions ... -
Study of the main variability aspects of surface texture of steel in face milling
Petropoulos, G.; Pandazaras, C.; Stamos, I. (2003)The investigation of basic variability aspects in face-milled surfaces regarding roughness and waviness (surface texture) for various cutting conditions is attempted in this note. The inhomogeneity of the machined steel ... -
Surface anisotropy for monitoring the wear of IC engine cylinders
Pandazaras, C.; Petropoulos, G. (2004)The present work proposes a methodology for monitoring the wear of internal combustion engine cylinders. This could be useful in calculating the time at which maintenance should be done on such a tribosystem or in determining ... -
Tribological design of hydrodynamic sliding journal bearings - formulating new functional charts
Pandazaras, C.; Petropoulos, G. (2005)Purpose - This paper aims to introduce an innovative methodology for the determination of operational characteristics of journal bearings (j-bs) through using new type charts based upon a numerical solution of the Reynolds ...
