The use of composite materials in critical aerospace structures is still limited by their relatively weak mechanical response to impact events. In addition, composite laminates subjected to low velocity impact such as dropped tools or vehicle impact, exhibit significant internal damage and delamination, with little indication on the impact surface that such damage has occurred, generally refered to in the industry as barely visable impact damage.You can see experimental figure of this impact at below
The projectile is modeled as three dimensional discrete rigid part and for modeling CFRP plates three dimensional space with continuum shell element has been used. Dynamic explicit is appropriate for this type of analysis. During the impact the projectile penetrated into the CFRP plates ans causes damage on them. You can see some figures of the results of this simulation at below
