ggplot to plot Mohr circle of rotated stress element

Description

Function plots a Mohr circle for a rotated stress element and indicates the pole and the rotation angles

Usage

ggplot_mohrcircle(
  sigz = 40,
  sigx = 20,
  tau = 10,
  theta = 0,
  rotation_label = "theta",
  face_label = c("X", "Z"),
  palette = "Set1",
  pole = TRUE,
  pole_label = "Pole",
  n_circle = 181,
  color_circle = "black",
  color_lines = "grey50",
  double_angle = FALSE,
  effective_stress = FALSE,
  clockwise_shear = FALSE,
  xlim = c(0, NA),
  ylim = c(NA, NA)
)

Arguments

sigz	normal stress on z-plane (scalar)
sigx	normal stress on x-plane (scalar)
tau	shear stress
theta	rotation, in radians (scalar)
rotation_label	label to use for rotation
face_label	labels for x- and z-faces
palette	RColorBrewer color palette to use
pole	plot the pole point, label and lines if 'pole = TRUE'. If 'pole = FALSE', do not plot anything related to the pole
pole_label	label to plot at pole
n_circle	number of points to use for drawing Mohr circle
color_circle	color of the Mohr circle
color_lines	color of lines crossing midpoint of circle
double_angle	if 'TRUE', an indicator for twice the applied rotation in is plotted in the Mohr circle. If 'FALSE', this is omitted
effective_stress	if 'TRUE', effective stress label is plotted on the x-axis. if 'FALSE', total stress
clockwise_shear	if 'TRUE', shear stresses are positive on positive faces of the element and when pointing in the positive direction. When 'FALSE', the default structural mechanics notation (right-hand rule for moments) is used instead, resulting in positive shear stresses pointing in the opposite direction. Function calculations assume ('clockwise_shear = TRUE')
xlim, ylim	user defined min and max x and y axis limits. If not defined, the are automatically chosen

Value

ggplot object

Examples

ggplot_mohrcircle(sigz = 40, sigx = 20, tau = 5, theta = pi/8)
