The paper deals with actual methodology and relevant technical regulation in the field of toughness (i.e. ductility) testing of fiber-reinforced concrete subjected to static load (flexural or wedge-splitting test), as well as testing of material's resistance to dynamic - impact load. The improved performance of fiber-reinforced concrete, compared to composite materials made without the addition of fibers, is most significant when the enhancement of fracture energy absorption capacity (i.e. improvement of toughness) is concerned. The results obtained during these tests can be very important, especially in order to compare the properties of different types of composites, but also to solve specific practical engineering problems.
U radu su obrađeni aktuelna metodologija i relevantna tehnička regulativa iz oblasti ispitivanja žilavosti (duktilnosti) mikro-armiranih betona pri statičkom opterećenju (savijanju ili cepanju pomoću klina), kao i otpornosti predmetnih materijala pri dinamičkom - udarnom opterećenju. Poboljšane performanse mikro-armiranih betona, u odnosu na kompozite spravljene bez dodatka vlakana, najviše su izražene u domenu povećanja njihovog kapaciteta da apsorbuju energiju tokom loma (tj. u vidu povećanja žilavosti). Rezultati dobijeni na osnovu ovakvih ispitivanja mogu da budu veoma značaj ni, pre svega kod poređenja svojstava kompozita različitog sastava, ali takođe i kod rešavanja specifičnih inženjerskih problema u praksi.
