Constitutive modeling of new synthetic hybrid fibers reinforced concrete from experimental testing in uniaxial compression and tension

Hybridization of fibers in concrete yields a variety of applications due to its benefits compared to conventional concrete or concrete with single type-fiber. However, the Finite Element (FE) modeling of these new materials for numerical analyses are very challenging due to the lack of analytical da...
