Product Overview:
Composite materials, despite their widespread use in aerospace applications, are still limited in critical structural roles due to their relatively weak mechanical response to impact events. When subjected to low-velocity impacts, such as those caused by dropped tools or vehicle collisions, composite laminates often experience substantial internal damage and delamination. This type of damage, known in the industry as Barely Visible Impact Damage (BVID), is typically difficult to detect as it shows minimal signs on the surface.

In the simulation, the projectile is defined as a three-dimensional discrete rigid element, while the CFRP (carbon fiber reinforced polymer) plates are modeled using a three-dimensional continuum shell element. A Dynamic Explicit analysis procedure is chosen as it is well-suited for capturing the behavior of materials during impact. During the simulation, the projectile penetrates the CFRP plates, leading to visible damage.

Learn the intricacies of simulating collisions involving Carbon Fiber Reinforced Polymer (CFRP) layers. Key topics include:

• Creating and configuring CFRP parts based on detailed material properties.
• Understanding the impact dynamics using Hashin Damage criteria.
• Efficiently managing assembly instances for accurate interaction setup.
• Techniques for analyzing outcomes such as damage distribution and structural integrity.
