Installation

Documentation

Mohr's circles are plotted on a matplotlib plot. If these circles are stresses at failure, a Mohr-Coulomb failure envelope can be estimated. More details can be found in https://e-mags.github.io/MohrCirclePlotter/

from mohrcircleplotter import MohrPlot

plot = MohrPlot(halfplot=True,show_tension=True, units='MPa')

# Define some circles (sigma_x, sigma_y, tau_xy)
circles = [
    (80, 30, 30),
    (60, 20, 20),
    (40, 10, 10)
]

for sigma_x, sigma_y, tau_xy in circles:
    plot.oriented_circle(sigma_x, sigma_y, tau_xy)

# Estimate and plot the Mohr-Coulomb failure envelope
plot.estimated_mc_envelope()
