CHARACTERISTICS OF AA6061-T4 AND -T6 EXTRUSIONS. Edition No. 1
VDM Publishing House, June 2009, Pages: 236
The main focus of this research was to investigate
force/displacement response and energy absorption
performances of axially loaded AA6061 T4 and T6
circular aluminum alloy extrusions under cutting
deformation mode. Quasi-static experimental
investigation on load/displacement and energy
absorption characteristics under cutting deformation
mode was completed utilizing specially designed
heat-treated 4140 steel alloy cutters and two
different geometries of the cone-shaped deflectors.
An almost constant force during cutting was observed,
which eliminated high peak crush force associated
with progressive folding or global bending
deformation modes. Additionally a dual stage cutting
process was initiated using two cutters in series in
this research. In addition to cutters and
deflectors, spacers of different geometries between
the cutters were also incorporated in this study.
Finally to this research, a numerical study of the
axial cutting deformation process was simulated
employing an Eulerian and Smoothed Particle
Hydrodynamic (SPH) methods.
