Simulation ballistic impact of steel bullet to the ceramic panel reinfroced with Green Composite

In this tutorial the Simulation ballistic impact of steel bullet to the ceramic panel reinfroced with Green Composite has been investigated. The bullet is modeled as a three-dimensional solid part, the ceramic panel as a solid part, and the green composite as a three-dimensional shell part. You can see a figure of the assembled part below

To model steel bullet material with rapid deformation, Johnson-Cook plasticty and damage is selected. The Johnson-Cook plasticity model is a particular type of Mises plasticity model with analytical forms of the hardening law and rate dependence, and suitable for high-strain-rate deformation of many materials, including most metals. Abaqus/Explicit provides a dynamic failure model specifically for the Johnson-Cook plasticity model, which is suitable only for high-strain-rate deformation of metals

To model Ceramic behavior Johnson-Holmquist consitive model is considered,  the JH-2 model assumes that the damage variable increases progressively with plastic deformation. To model green composite with several layup, Hashin’s damage criterion is used. 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

Dynamic explicit step with specific time durition is appropraite for this type of analysis. The general conctact algorithm with contact property amoung all parts is selected. To define the contact between ceramic panel and green composite plate, the Tie constraint is used. The fix boundary condition for ceramic panel and initial velocity for the bullet in the load section are applied. The mesh should be fine to get proper results. After the analysis, all results such as stress, strain, damagae, crater, depth of penetration, force, … are avaiable. You can see some figures below for the results
