Webpenetration, even for the highest hardness armours, since the penetrator remains rigid when its hardness exceeds 1.5 times the hardness of the target [7]. The deformation of the ball round and the rigidity of the AP penetrator are seen in Fig. 2. Further details of the projectiles may be found in Ref. [8]. Armoured steel must be hard, yet resistant to shock, in order to resist high velocity metal projectiles. Steel with these characteristics is produced by processing cast steel billets of appropriate size and then rolling them into plates of required thickness. Hot rolling homogenizes the grain structure of the steel, changing the crystalline structure of the steel and normalizing it. RHA is homogeneous because its structure and composition are uniform throughout its thicknes… dexter lee williamsWeb8 de ago. de 2008 · Ballistic performance of engineering materials should be known in selection of the most suitable armor material to protect civilian or military system with the … church terrier and inventory
