Abstract:
The response over the low-velocity impact of various shape impactors on a glass
fiber reinforced polymer composite has been numerically analyzed with a
hemispherical, flat, partially flat and truncated shaped impactor used to analyze
the behavior of resistance of a GFRP composite at various speeds. The numerical
analysis was carried out using finite element analysis software, ABAQUS
(Dynamic/Explicit). To assess the response of the composite laminates while
impacting, finite element models were developed. The Hashin failure criteria
were used to represent braided glass-fiber reinforced composite plate damage.
Regarding projectile shape, the impact reaction of the composite was examined.
The results also show that the mechanical response of woven glass fiber
polymer composite under low-velocity projectile impact largely depends on the
impactor’s nose shape and the velocity of the impactor.
