Rolled homogeneous armor
Rolled homogeneous armor (RHA) is a type of armor made of a single steel composition, as opposed to layered or cemented armor. Its first common application was in tanks.

A target consists of one SiC tile glued to a rolled homogenous armor (RHA) steel plate of 40 mm thickness. Depending on the impact velocity, additional RHA plates are placed behind the target, in order to ensure a semi-infinite RHA target for penetration measurement. Table 1 shows the key mechanical properties for the different materials.
