The influence of target thickness and projectile size on the projectile impact damage generated on SiC targets is investigated. The projectile impact generates several types of damage such as a ring crack, a crater or a cone crack. In the case of thick targets, the residual strength of the targets does not depend on target thickness. This is due to that damage is generated only near the impacted surface. On the other hand, in the case of thin targets, the residual strength drops drastically. This is due to the generation of "back surface cracks." In addition, the projectile size affects the residual strength and the cone crack size. However, the minimum impact velocity at which ring cracks are generated does not change with projectile size.
