Abstract
<div class="section abstract"><div class="htmlview paragraph">Over the years the vehicle population has drastically grown which increases the
number of road accidents. The accident severity caused fatality and disability
being reduced by introducing energy absorption materials (Crash tube). Over the
years, researchers have used aluminium, magnesium, and titanium crash tubes to
enhance the energy absorption characteristics during different crash scenarios.
However crash tube will possess sufficient rigidity to absorb the impact force
during collision but it is still challenging to identify the right material. At
the same time, this paper aims to examine the energy absorption characteristics
of Aluminium-Magnesium hybrid material (Al-Mg 5456) crash tube designs. Three
designs were considered square, cylindrical, and hexagonal designs along with
different notch designs to minimize the weight percentage of tubes. The LSDYNA
results the oval notches performed better in energy absorption when compared to
other designs. Hence, the present findings can satisfy the future needs that are
required for electric vehicles and can be a leading-edge innovation in the
upcoming automotive industry.</div></div>
