“…In order to consider strain rate effect, yielding stress expressed in Eq. 2 is varied using the strength enhancement ratio proposed by Fujikake et al [4,5]. Dynamic compressive strength and tensile, corresponding to the yielding strength, is calculated by multiplying dynamic enhancement factor to static compressive and tensile strength, respectively.…”

“…Even though applications of UFC material is reported as the structural member of pedestrian bridges, highway bridges at nowadays, only a few researches are conducted to evaluate its dynamic material behaviors. Hence, in order to investigate the effect of high strain rates of UFC material, the triaxial compressive and uniaxial tensile test under rapid loading have been carried out by Fujikake et al [4,5]. Furthmore, the rapid flexural loading test and drop hammer impact test of UFC material beam structure have also been conducted to evaluate impact response.…”

This study presents the local damage of ultra high strength fiber reinforced concrete plates. Impact test of the reinforced concrete plates using two different short fibers are conducted to examine the failure behavior and impact resistant performance. Material models are discussed and proposed by simulating the high speed tri-compressive and uni-tensile tests. Numerical simulations of the impact tests are carried out. Numerical results show good agreements with the test results.

“…Several studies focused on the material property of UHPFRC reinforced with short steel fibers. Fujikake et al (2006aFujikake et al ( , 2009 and Noldgen et al (2013) conducted rapid-speed triaxial compressive tests, rapid-speed uniaxial tensile tests, and split Hopkinson pressure bar tests, respectively. They formulated the dynamic mechanical properties of the UHPFRC.…”

This study investigated local failure characteristics and failure limit thicknesses of an ultra-high-performance fiber-reinforced concrete panel reinforced with polyvinyl alcohol by conducting impact tests. In a series of tests, steel hemispherical projectiles with a mass of 46 g collided with ultra-high-performance fiberreinforced concrete panels reinforced with polyvinyl alcohol. The ultra-high-performance fiber-reinforced concrete panels reinforced with polyvinyl alcohol with thicknesses in the range of 30-90 mm were tested at the impact velocities of 170-500 m/s. The experimental results revealed that the penetration depth or scabbing damage induced by the impact was significantly suppressed for the ultra-high-performance fiberreinforced concrete panel reinforced with polyvinyl alcohol compared to that of a plain concrete panel. The experimental results demonstrated that local failure intensity for the panels was similar at equivalent impact energies, regardless of the combination of projectile mass and impact velocity. Based on the test results, we proposed a method for evaluating the penetration depth and scabbing limit thicknesses by the impact energy.
