Question

use matlab to plot

2-8 The stress-strain data from a tensile test on a cast-iron specimen are Engineering stress, kpsi 5 10 16 19 54 26 32 40 46 49 Engineering strain. | 103in/in 0.20 0.44 0.80 1.0 1.5 5.0 2,0 2,8 3.4 4.0 Plot the stress-strain locus and find the 0.1 percent offset yield strength, and the tangent modulus of elasticity at zero stress and at 20 kpsi

Answer 1

`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

clear, clc
E=[5,10,16,19,26,32,40,46,49,54];
e0=[0.2,0.44,0.8,1,1.5,2,2.8,3.4,4,5]*1e-3;
plot(e0,E);
xlabel('Strain');
ylabel('Stress');
title('Stress Strain plot');
