Creation[edit]
This file was created with Python, SciPy, NumPy and Matplotlib. The data was obtained from the following image
import numpy as np
from scipy.interpolate import interp1d
import matplotlib.pyplot as plt
from matplotlib import rcParams
rcParams["font.family"] = "serif"
rcParams["font.size"] = 14
cycles = np.logspace(0, 7, 8)
stress = np.array([320, 300, 260, 200, 150, 120, 96, 80])
f = interp1d(np.log(cycles), stress, kind="cubic")
new_cycles = np.logspace(0, 7, 100)
new_stress = f(np.log(new_cycles))
plt.figure(figsize=(10,6))
plt.semilogx(cycles, stress, "ko")
plt.semilogx(new_cycles, new_stress, "k")
plt.grid(True, lw=1, alpha=0.6)
plt.ylim([0, 350])
plt.xlabel("Life (cycles)")
plt.ylabel("Stress (MPa)")
plt.title("S-N Curve for Brittle Aluminium with a UTS of 320 MPa")
plt.savefig("BrittleAluminium320MPa_S-N_Curve.svg")
