Simulation rigid impact to the composite panel(CFRP+TPU+AL) in Abaqus-Damage investigation

In this tutorial, the Simulation rigid impact to the composite panel(CFRP+TPU+AL) in Abaqus-Damage investigation – has been studied. The CFRP part is modeled as a shell part with eight layers. The Thermoplastic polyurethane is modeled as a three-dimensional solid part. The Aluminum part is modeled as a three-dimensional solid part. The projectile is modeled as the rigid shell part. Because of the symmetry, one-quarter of the model is used. You can see a figure of the assembled parts below

To model CFRP behavior under the rigid impact, elastic property with Hashin’s damage criterion 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 aluminum behavior, elastic data with Johnson-Cook hardening and damage is used. 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 TPU behavior, the elastic-plastic material model with ductile damage criterion is selected

The dynamic explicit step is appropriate for this type of analysis. The perfect contact is assumed between TPU-AL and TPU-CFRP surfaces. The general contact with contact property is considered between the rigid body and other parts. The fixed boundary condition is assigned to the outer edges and the symmetry boundaries to the symmetry zones. The mesh should be fine to obtain the correct results

After the simulation, all results such as stress, strain, CFRP damage, aluminum damage, TPU failure, …are available. You can see some figures for the results below
