Simulation of a steel bullet impact on the composite panel(Boron carbide-CFRP-Gelatin) in Abaqus

In this tutorial, the Simulation of a steel bullet impact on the composite panel (Boron carbide-CFRP-Gelatin) in Abaqus has been investigated. The bullet is modeled as a three-dimensional solid part. The boron carbide and gelatin are modeled as three-dimensional solid parts. The CFRP is modeled as a shell with eight layers. You can see a figure of the assembled parts below

Boron carbide, (B4C), is the crystalline compound of boron and carbon. It is an extremely hard, synthetically produced material that is used in abrasive and wear-resistant products, in lightweight composite materials, and control rods for nuclear power generation. To model Boron carbide material, the Johnson Holmquist model is selected. Damage initiation refers to the onset of degradation at a material point. In Abaqus, the damage initiation criteria for fiber-reinforced composites are based on Hashin’s theory. These criteria consider four different damage initiation mechanisms: fiber tension, fiber compression, matrix tension, and matrix compression. To model gelatin tissue behavior, the elastic and plastic data are considered. For the steel bullet, the elastic-plastic model and damage criterion are used

The dynamic explicit step is appropriate for this type of analysis. The perfect contact is assumed among the panel surfaces and the surface-to-surface contact between the bullet and the top layer. The Boron carbide should absorb the impact energy to reduce the damage in the second and third layers. The proper symmetry boundary conditions are assigned to the parts. The mesh should be fine to obtain the correct results

After the simulation, stress, strain, damage, failure, penetration, energy dissipation, gelatin deformation, and other results are available. You can see some figures for the results below
