The friction coefficient in the simulation of stamping processes should be defined. Modern software allows its definition as constant or dependence on pressure temperature. It is also useful to define different values regions, it often reflects nature deformation process. This article deals with regression and analytical models commonly used determine coefficients specified areas Analytical wer...

This study demonstrates the possibility of using sanitizing detergents based on natural products for the elimination and/or reduction of Aeromonas hydrophila biofilm formed on stainless steel surfaces. The goal of this work was to determine the reduction effect of sanitizing detergents containing essential oils of Thymus vulgaris (thyme) and Cymbopogon citratus (lemongrass) on biofilm formed by...

In recent years, the need for eco-friendly machining processes has increased dramatically in order to limit excessive use of conventional cutting fluids, thereby reducing their negative effects on both environment and operator’s health. this context, environmental alternatives such as dry cutting, minimum quantity lubrication (MQL), nanofluid-assisted MQL have been demonstrated be effective ove...

in this paper, welding feasibility between aa1100, aa5050 and aa6082 aluminum alloys and a441 aisi steel by friction stir welding has been studied. mathematical analysis of the heat generation during process showed that the maximum temperature produced in aa6082 aluminum alloy and a441 aisi joint but heat distribution in aa1100 aluminum alloy was higher than the other alloys. the investigation ...
