Three-Dimensional Finite-Discrete Element Framework for the Fracturing of Reinforced Concrete Structures

Three-Dimensional Finite-Discrete Element Framework for the Fracturing of Reinforced Concrete Structures

This paper presents a three-dimensional numerical model based on finite-discrete element method for simulating cracking and predicting failure in reinforced concrete (RC) structures. Discrete representation of concrete cracks is coupled with a non-linear reinforcement model where reinforcing bars in...
