This tool generates randomly oriented fibers. Then, Autocad DXF file is created for the generated fibers. The algorithm takes into account fibers diameters for ovelap checking with other fibers. Example files are provided for the simulation of notched beam "Example_Beam.m" ,cylinder "Example_Cylinder.m", and cube "Example_Cube.m".
Important Note: This tool requires DXFLib (tested with version 1.2.0.0). The user should download it and put its files in the same folder of this tool. The link for DXFLib is:
functions:-
[Nodes_Fibers, Fibers]=Generate_Fiber(x,y,z,L,N,DFiber,Orientation,Ndiv);
Plot_Fiber(x,y,z,Nodes_Fibers,Fibers,DFiber);
Fiber2DXF(Nodes_Fibers,Fibers,Filename);
Input:
x,y,z: as vectors defining the specimen dimension. x and z are vectors defining a polygon section in xz plane and y=[ymin ymax] is boundaries of the extrusion of the polygon
L: Length of fibers
N: Number of fibers
DFiber: Diameter of fibers
Orientation: can be either:-
-For aligned fibers Orientation=[l m n] where l,m, and n are the direction cosines of the fibers orientation in x,y, and z directions, respectively.
- For random fibers Orientation=[] (empty)
Ndiv: Number of fiber mesh divisions
Filename: name of the DXF file with the extension.
Output:
Nodes_Fibers: ((Ndiv+1)*N,3) matrix of fibers nodes coordinates.
Fibers: (N,2) matrix of the two nodes indices connecting each fiber segment.
