ggplot influence factors for stress underneath triangular strip foundation

Description

Creates a ggplot chart with contour lines and heat map (optional) for the influence factors for stress underneath a triangular strip load. Assumes elastic solutions are valid

Usage

ggplot_stress_triangularstrip(
  direction = "z",
  nu = 0.3,
  xlim = c(-1, 2),
  ylim = c(0, 3.5),
  gridsize = 0.05,
  contour_width = 0.1,
  contour_label = c(0, 0.1, 0.2, 0.4, 0.6, 0.8, 1),
  showgrid = TRUE,
  larrow = 0.3,
  lsize = 3.5,
  labelsize = 3,
  palette = "Blues",
  xB = NULL,
  zB = NULL,
  nround = 3
)

Arguments

direction	the direction of the stress of interest. 'z' for vertical, 'x' for horizontal away from strip, 'y' for horizontal in direction of strip, and 'xz' for shear stress
nu	Poisson's ratio, required for stress in y-direction
xlim	2-value array with limits for x-axis
ylim	2-value array with limits for depth axis
gridsize	grid size for calculations
contour_width	I-interval between contour lines
contour_label	values of I for which to draw contour lines
showgrid	if 'TRUE', heatmap of influence factors is shown in background of the plot
larrow	length of load arrows (in normalised coordinates)
lsize	thickness of load arrows
labelsize	size of labels on contour lines
palette	RColorBrewer palette for heat map
xB	crosshairs annotation
zB	crosshairs annotation
nround	number of decimals in crosshairs I label

Value

ggplot object

Examples

#plot empty chart
ggplot_stress_triangularstrip()

#plot with annotation
ggplot_stress_triangularstrip(xB = 1, zB = 2)
