Generate Thick Fibers
Version 1.0.2 (6.11 KB) by Ayad Al-Rumaithi
Generate random fibers taking into account fibers diameters
Updated 11 Mar 2023
Generate randomly oriented fibers inside a box with example file. 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".
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
Nodes_Fibers: ((Ndiv+1)*N,3) matrix of fibers nodes coordinates.
Fibers: (N,2) matrix of the two nodes indices connecting each fiber segment.
