Abstract: (1662 Views)
In the present paper, the problem of low velocity impact of plates made from different configurations of ceramic, aluminum, steel and composite (S-glass polyester) is analyzed numerically using Abaqus finite element software. The projectile is assumed to be a rigid body with a hemispherical head. Also, for ceramic layers, Holmquist constitutive model, for aluminum and steel layers, Johnson Cook behavioral model and for composite layer, three-dimensional Hashin model is used to model the material behavior. After doing the low velocity impact simulation for the composite target, comparing it with previous researches and ensuring the accuracy of the results, the low velocity impact simulation is performed for metal, ceramic and composite targets with different configurations. The results indicate that the target plate with ceramic-steel-composite configuration has the highest impact strength and the projectile penetration is reduced in this case.
