Hi Muhammad,
From your query, I understand that you want to plot the S-N curve for the given materials. For this you can utilize the ‘plot’ function available in MATLAB. I have shared the sample code snippet below, which demonstrates the creation of S-N curve for Aluminium using random data.
% Data for S-N curve (stress vs. number of load cycles to failure)
% Format: [stress1, N1; stress2, N2; ...]
aluminium_data = [50, 2000; 100, 1000; 150, 500; 200, 200];
% Plot S-N curve for Aluminium
plot(aluminium_data(:, 2), aluminium_data(:, 1), 'b', 'LineWidth', 2);
% Set plot labels and title
xlabel('Number of Load Cycles to Failure (N)');
ylabel('Stress (S)');
title('Stress-Load (S-N) Diagram');
If you want to plot multiple curves into single graph, you can utilize ‘hold on’ and ‘hold off’ commands.
For better understanding of how to use ‘plot’ function, please refer to this MATLAB documentation:
Hope this helps!
