STEEL FIBER CURVATURE IN CONCRETE COMPOSITES: MODULUS PREDICTIONS USING EFFECTIVE STEEL FIBER PROPERTIES [PDF]
American Journal of Applied Sciences, 2014 Results in the literature demonstrate that substantial improvements in the mechanical behavior of concrete have been attained through the addition of steel fibers as a reinforcing phase. We have developed a model combining finite element results and micromechanical methods to determine the effective reinforcing modu-lus of hook-ended steel fibers. This
