Compared with the finite element method, the simplified model is feasible under the condition of low impact speed.
At an impact speed of nearly 100 m. p. h. , the stone exploded through the Honda's windshield, slamming into the left side of Herring's head.
The results show that the abrasion of coatings was influenced by many factors, such as attack angle, impact speed, and abradant dosage etc.
