Effect of Interface Elastic Modulus on Damage Mechanism of the Fiber Reinforced Concrete
This research focuses on the interface’s impact on the macro-mechanics and damage mechanism of the fiber reinforced concrete (FRC). In consideration of the mesoscopic nonhomogeneity of the interface, numerical test has been adopted to simulate failure procedure of fiber reinforced concrete samples. It can, therefore, be concluded, that, the interface elastic modulus have a great impact on the macro-mechanics of the FRC. With interfaces added into FRC, failure could present ductile properties, cracks could be developed horizontally, and then unbonded and slid along the interface. During the process, phenomenons such as interface debonding and sliding, crack deflection, fiber bridging and pulling out could be clearly observed. Under With the premise that strength for interface is adequate for stress transferring, the toughness of the FRC would be enhanced by the interface.
