STRENGTH  ANALYSIS  FOR  STEEL  FIBER-CONCRETE  SLABS  UNDER  SHOCK-WAVE  EXPOSURE

Continuum mechanics was used to design a mathematical model for deformation and fracture processes in steel fiber-concrete under shock-wave exposure. Impact interactions between a steel bar and slabs were investigated by means of computer simulation of impact velocity ranged between 100–500 m/s. The behavior of concrete, steel fiber-concrete, and armed concrete slabs is studied in this paper.

Keywords: shock-wave exposure; steel fiber-concrete; concrete; armed concrete; dynamic fracture; mathematical modeling.
