Fiber-Reinforced Concrete Finite Element Solver

Fiber-Reinforced Concrete Finite Element Solver

Fiber-Reinforced concrete finite element solver based on the mesoscale model described in the reference [1]. Example files for the analysis of FRC beams subjected to three-point bending tests are provided in the folder Run Flexure as follows:

1-Example_One_Realization.m: executes one realization of the analysis.

2-Example_Multiple_Realizations.m: executes multiple realizations of the analysis, then the results are saved in a folder.

3-Example_Multiple_Realizations_Size_Effect.m: executes multiple realizations of the analysis for a certain size scale, then the results are saved in a folder.

4-Example_Multiple_Realizations_Size_Effect_Meso_Macro.m: executes multiple realizations of the analysis for a certain size scale, then the results are saved in a folder. In order to save computation time for large size scales, steel fibers are simulated only in the center of the beam near the notch location.

In the above examples, Orientation=[]; which means the fibers are randomly oriented. In order to generate alligned fibers, change Orientation variable to the following values:

1-Alligned to x-axis: Orientation=[1 ; 1e-6 ; 1e-6];

2-Alligned to y-axis: Orientation=[1e-6 ; 1 ; 1e-6];

3-Alligned to z-axis: Orientation=[1e-6 ; 1e-6 ; 1];
