The tests were conducted on thick block specimens using non-deformable ogive-nosed projectiles with a mass of 250 g and a diameter of 28 mm at approximately 400 m/s.
The severity of damage was quantified by the depth of penetration (DOP), equivalent crater diameter (ECD), crater volume (CV), and crater profile (CP).
The energy absorption capacity under direct tension is found to be more relevant than flexural toughness in controlling CV and CP.
Transient temperature under HVPI is likely elevated to about 250 °C in the ultra-high performance fiber reinforced concrete (UHPFRC), which may lead to higher internal pressure built-up (thus damage) than the engineered cementitious composites (ECC).
