Numerical Simulation of Crack Propagation in Fiber Reinforced Polymer Concrete Composites in the high Temperatures

Fiber Reinforced Polymer Concrete composite materials have been widely used in many fields of engineering, it is necessary to research the crack propagation process of Fiber Reinforced Polymer Concrete composite material in the high temperature by Numerical Simulation. the numerical model is applied to investigate the formation, extension and coalescence and crack propagation in Fiber reinforced polymer reinforced concrete composites in the high temperature, the deformation and damage evolution are briefly described in the model, a numerical model of fiber reinforced polymers embedded in Concrete is proposed to investigate thermally-induced damage and crack propagation in the high temperature, the numerical Simulation show that the crack propagation behavior of the Fiber Reinforced Polymer Concrete composite material in the high temperature is developed at the interface between the Fiber Reinforced Polymer and Concrete, the numerical simulation demonstrates that the model proposed can visually replicate the thermal cracking propagation process of Concrete and the simulated cracking of Concrete is in good agreement with the experimental cracking result of Fiber Reinforced Polymer Concrete composite material in the high temperature.
