hardness of crinoidal limestone

EOI tests were also performed oncrinoidal limestone. A slab of size 300 × 150 × 15 mm 3 is impacted on the edge by an aluminum alloy projectile (diameter: 20 mm, length: 50 mm) traveling at 100 m/s. A typical damage pattern is shown in Fig. 4.2. It is composed of a network of radial and hoop cracks.
