**Figure A3.** Damage caused by the conical striker at different instances of the simulation: (**a**) time = 0.1 ms, (**b**) time = 0.2 ms, (**c**) time = 0.3 ms, (**d**) time = 0.35 ms.

**Figure A4.** Damage caused by the hemispherical striker at different instances of the simulation: (**a**) time = 0.05 ms, (**b**) time = 0.1 ms, (**c**) time = 0.15 ms, (**d**) time = 0.2 ms.

**Figure A5.** Damage caused by the blunt striker at different instances of the simulation: (**a**) time = 0.05 ms, (**b**) time = 0.1 ms, (**c**) time = 0.12 ms, (**d**) time = 0.15 ms.

**Figure A6.** Damage caused by the ogival striker at different instances of the simulation: (**a**) time = 0.1 ms, (**b**) time = 0.2 ms, (**c**) time = 0.3 ms, (**d**) time = 0.35 ms.
