A Practical Engineering Algorithm on the Calculation of SFRC Penetration Depth

The studies on SFRC penetration properties are rare now, especially there is no effective formula on penetration depth. In this paper, quasi-static and dynamic uniaxial compression tests on SFRC specimens were carried out, and toughness effects were analyzed. The results show that toughness is one of the main factors which influence penetration depth. Toughness can be characterized by <i<ρ</i<<sub<f</sub<<i<l</i<<sub<f</sub</<i<d</i<<sub<f</sub<, penetration formula of SFRC was got by dimension analysis, and coefficients were defined by actual penetration tests by <i<Φ</i<30 gun. Thus practical engineering algorithm on SFRC penetration depth was brought out.
