Physical modelling of variable contact pressure and variable drawbead height influence on deep drawing of thin sheets [PDF]

open access: yes, 2011
For this experimental research, electro-hydraulic computerised device for sheet metal stripes sliding was made. Its main property is realisation of contact pressure and drawbead height as functions dependent on time, i.e. stripe travel.

Corrosion Behaviour of the As-Cast and Heat-Treated Za27 Alloy [PDF]

open access: yes, 2011
Corrosion behaviour of the as-cast and heat-treated ZA27 alloy was examined. The alloy was prepared by conventional melting and casting route and then thermally processed by applying T4 heat treatment regime (solutionizing at 370 C for 3 hours followed ...

Characteristics and limitations of physical tribo-modelling in deep drawing of thin sheet metal [PDF]

open access: yes, 2015
The significance of contact friction in deep drawing is well-known, especially in manufacturing of auto body parts. The general approach in this area involves the recognition of the influence of the main tribological parameters – pressure, speed and ...

Experimental Determination of the Wear Factor of the Sliding Bearings Made of Polymer Based Composite [PDF]

open access: yes, 2017
Wear intensity is very important in terms of determining life cycle of machine elements. Experimental analysis of wear factor of certain material in contact with other specific materials are inevitable for this prediction. This paper provides two methods
