- This Python code creates 2D RVE of random distributed discontinues fibers in a rectangle. Fibers have different lengths and orientations. The code uses exact checking the intersection between fibers with a specified tolerance. The code creates fibers in opposite side of the RVE in the case that a fiber intersects the boundary. Material properties and orientations are assigned to each fiber separately. Then the boundaries are meshed in a way that applying PBC is possible. PBC are applied by MPC constraints.
- This code is best suited for meso scale modeling of short random distributed fiber reinforced composites. Please note that the maximum fiber volume fraction depends on the fiber aspect ratio and for large aspect ratios high fiber volume fraction is not possible by these types of modeling.
- This python script can create RVE of short fiber composites. The fiber location, orientation and length are random. The intersection between fibers are checked and prevented in a simple way. Then, material properties are assigned to each fiber. Material orientation is also assigned to each fiber based on its angel.
- Please not that this file is for education and has some limitations for academic projects. For example, this file checks the intersection in a simple way that reduces the volume fraction. Intersection of fibers with boundaries also are not implemented in this file.
