Recenzovaný Použitie nedeštruktívnej akustickej emísie a numerickej analýzy na sledovanie deformácií vláknobetónu 1x 0.25x 0.5x 0.75x 1x 1.25x 1.5x 2x Cieľom výskumu bolo overiť možnosť využitia nedeštruktívnej metódy akustickej emisie na posúdenie stavu betónu bez rozptýlenej výstuže a s rôznym obsahom pridaných zakrivených oceľových vlákien. Počas experimentu bola vykonaná aj deformačná analýza pomocou MKP.

1. Introduction As is well known, it is possible to add polypropylene fibers to the concrete mix to ensure ductility, improve mechanical properties, and extend durability. This creates polypropylene-fiber-reinforced concrete (PPFRC). Thus, from a simple material, concrete becomes a complex solution that can be adapted to specific applications [1,2].
