Cone formation in targets beneath a penetrating projectile

Characterising failure in textile-reinforced thermoplastic composites by electromagnetic emission measurements under medium and high velocity impact loading

“…Indirect parameters such as the identification of the delaminated area or fibre failure are usually determined thereafter by nondestructive evaluation methods such as ultrasonic (US) inspections and computed tomographic (CT) analysis [7,20] but do not reveal information regarding the impact damage process. Also, a widely used approach is to relate the characteristics of the energy redistribution in the investigated impact system and its collision parameters to the value of residual deformations [21,22].…”
