(
Elsevier, Ltd
, 2014 , Article)
Abstract This study was undertaken to investigate the influence of Al–8B master alloy and modified strain-induced melt activation process on the structural characteristics and dry sliding wear behavior of Al–12Zn–3Mg–2.5Cu ...
Crushing behavior of hybrid hexagonal/octagonal cellular composite system: All made of carbon fiber reinforced epoxy
(
Elsevier, Ltd
, 2014 , Article)
Cellular carbon fiber-reinforced plastic (CFRP) composites, either unfilled or filled with foam, may be of interest for energy absorption application due to their improved crashworthiness. In the current paper, new ...
Axial crushing behavior and energy absorption efficiency of corrugated tubes
(
Elsevier, Ltd
, 2014 , Technical Report)
This paper presents the effect of corrugations on the crushing behavior, energy absorption, and failure mode of circular aluminum tubes. Experimental investigations were carried out on five geometrical types of corrugated ...
Modelling of the flow behaviour of wrought aluminium alloys at elevated temperatures by a new constitutive equation
(
Elsevier, Ltd
, 2014 , Article)
The hot working behaviour of an Al–0.7%Mg–0.4%Si (wt.%) aluminium alloy has been investigated by torsion testing in the 450–575°C temperature range. The behaviour of the alloy, in terms of equivalent stress vs equivalent ...
