Aggregate packing generator used for the simulation of aggregate in composites. It can be used especially for meso-scale analysis of concrete and asphalt composites .Example file is provided for the simulation of hollow cylinder "Example.m"
1-Classes=Particles_Generation2(x,y,z,x2,y2,z2,Classes_diameters,Classes_particle_ratios,m)
Generates aggregates according to defined volumetric ratios for each diameter.
2-function Ellipsoids=Particles_Distribution2(Classes,x,y,z,x2,y2,z2,er)
Generates aggregate with ellipsoids shapes
3-function Plot_Ellipsoids(Ellipsoids,x,y,z)
Plots ellipsoids
where the variables defined as:
input:
x,y,z: as vectors defining the specimen dimension. x and y are vectors defining a polygon section in xy plane and z=[zmin zmax] is boundaries of the extrusion of the polygon
x2,y2,z2: as vectors defining the hole dimension to be substracted from the shape of (x,y,z). x2 and y2 are vectors defining a polygon section in xy plane and z2=[zmin2 zmax2] is boundaries of the extrusion of the polygon
Classes_diameters: Particles classes diameters vector (descendingly)
Classes_particle_ratios: Particles volumetric ratio for each class (descendingly)
m: Particles shape distribution factor. m=1 for spheres and m>>1 for elongated ellipsoid shapes.
er: Spacing factor between particles to avoid contact [0.05-0.1].
Classes: A variable containing generated particles and not yet packed into specimen
Ellipsoids: (N*9) array. each column represent:
(:,1): radius of ellipsoids at direction 1
(:,2): radius of ellipsoids at direction 2
(:,3): radius of ellipsoids at direction 3
(:,4): x-cooridante of centroid
(:,5): y-coordinate of centroid
(:,6): z-coordinate of centroid
(:,7): Inclination angle 1
(:,8): Inclination angle 2
(:,9): Inclination angle 3
