I need help in creating a stress-load diagram of three different materials

I need help in creating a stress-load diagram of three different materials

Material 1 = Mild Steel

Material 2 = Brass

Material 3 = Aluminium

Please help me to find the code, i need have S-N curve graph.

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!
