In GJMeijer/soilmech: R functions and plots for Soil Mechanics teaching

Create a random packing of particles

Description

Creates a random plot of particles

Usage

random_packing(
  porosity = 0.3,
  dmax = 0.4,
  dmin = 0.02,
  width = 1,
  height = 1,
  clip = TRUE,
  nc = 91,
  npos = 100^2,
  npar = 1000,
  fill_soil = "#d3bc5f",
  color_soil = "#65571d",
  size_soil = 0.5,
  size_border = 1
)

Arguments

porosity	target porosity (fraction)
dmax	maximum particle diameter
dmin	minimum particle diameter
width	soil element width
height	soil element height
clip	if 'TRUE', particles partially sticking out of sample are cropped to the soil element
nc	number of points on each particle circle
npos	max number of grid positions to choose from
npar	max number of particles
fill_soil	color of fill of soil cube
color_soil	color of outline of soil cube
size_soil	thickness of particle border
size_border	thickness of soil element border

Value

a ggplot object

Examples

#loose sample
random_packing(porosity = 0.35)

#dense sample
random_packing(porosity = 0.15)
