In this study, we've developed a new theoretical methodology
that enables the design of protective structures
using the new generation of printed metallic materials.
We prove that in this kind of material,
porosity does not contribute to failure
at high strain rates.
At high strain rates mechanical failure is governed
by inertia,
so we bring to light how material fails,
so the possible application, they can use it
to improve the manufacturing process.
The results we've obtained
can be very relevant to several engineering sectors.
Typically, these include security,
aerospace or transport.
For example, if we are talking about protective structures
in industrial facilities such as nuclear power plants,
it's critical that structures are able to withstand stress
such as explosions and impacts without any fragmentation.
On the other hand,
we also find its application in the aerospace industry,
where structure fragmentation is desirable.
The clearest example
is with space debris,
which enters the Earth's atmosphere and falls to the surface.
The aim is for fragmentation to occur during this reentry process,
ensuring that the structures that reach the surface are not large in size.
This research is limited within the framework of the Outcome project,
in which we are training doctors
in protection structure analysis
for civilian and aerospace industries,
in collaboration with researchers
from the Israeli Institute of Technology
and Texas A&M University of College Station in the United States.
