Abstract:
Military personnel, Law enforcement agencies, and Individuals employed on security
duties require the highest level of protection when dealing with the lethal physical,
chemical, and biological threats. Protective gears requirement is increasingly focused on
ballistic protection level, anti-stabbing, and anti-biological protection. Ballistic effect onto
woven flexible composites is a very complex problem given the structural binding of the
materials, projectile’s impact velocity, material anisotropic behavior, and given boundary
conditions. Ballistic products undergo degradation and disintegration with the passage of
time due to actual operating conditions, usage, environmental conditions and storage
techniques.
The main objective of this thesis is to forecast the strength and durability of the soft
ballistic inserts which are made up of the fibers of “Ultra-High Molecular Weight
Polyethylene” (UHMWPE). This study introduces a sequence of tests to determine the
working life as well as to adapt to ballistic, physical, and mechanical properties resulting
from rapid conditions of operation, by using composite ballistic inserts simulation. This
research used data on the following ageing modeling techniques such as simulations for
the ballistic inserts. The effect of mechanical loading and temperature cycling, as well as
the solution simulating human transpiration, has been shown to affect and speed up the
process of Polyethylene (PE) Depletion. Samples of Ballistic products were analyzed
under specific conditions for 5, 7, 9, and 13 years in order to determine the connection
and association between the normal ageing mechanism and the simulated ageing
mechanism. In order to model and simulate ballistic impacts, ANSYS Workbench
Explicit Dynamics (R1 2020) and SolidWorks (2018) were used. The simulation was
based on systematic research by using the experimental approach and reference outcomes
to evaluate composite armor ageing behavior
