Abstract (english)

Concrete is very strain rate sensitive material, especially in tension. In this work the effect of dynamic loading on concrete properties in terms of rate dependent failure mode, resistance, tensile strength and fracture energy will be presented. Through own experiments and numerical modeling of L-specimen it is shown that inertia effects are responsible for progressive increase of resistance and rate dependent failure mode. Numerical results and their comparison with experiments show that the true fracture energy and tensile strength increases approximately linear in semi-log scale with strain rate and that approximately follow rate dependent constitutive law used in the computation
