Acousto-optic characterization of bending damage of pre-cut steel-polyvinyl alcohol hybrid fiber reinforced concrete

Acousto-optic characterization of bending damage of pre-cut steel-polyvinyl alcohol hybrid fiber reinforced concrete

This study investigates the flexural mechanical properties of pre-cracked steel-polyvinyl alcohol (PVA) hybrid fiber-reinforced concrete beams with varying fiber contents. Hybrid fiber composite materials were utilized, with PVA fiber volume fraction at 1.5 % and steel fiber volume fractions ranging...
