Numerical Modeling of Hybrid Fiber-Reinforced Concrete (HyFRC)

摘要: A model for numerical simulation of mechanical response concrete reinforced with slipping and non metallic fibers in hybrid form is presented this paper. Constitutive law used to plain behaviour based on plasticity damage theories, capable determine localized crack opening three dimensional (3-D) systems. Behaviour formulated effective stress carried by these after when matrix cracked. continuous approach proposed the effect addition non-slipping concrete. This considers constitutive increased fracture energy tension obtained experimentally direct tests Fiber Reinforced Concrete (FRC). To simulate fiber-reinforced (HyFRC), approaches nonslipping are simultaneously without any additive equation. All parameters have physical meanings determined through experiments or drawn from literature. The was implemented Finite Element (FE) Code “CASTEM” tested FRC prismatic notched specimens flexure. Model prediction showed good agreement experimental results.
