Whats the matlab function Steps pleaseSolutionplotstraintest

Solution

plot(strain_test,stress_test)

x0=xlabel(\'strain, \\epsilon (%)\');

y0=ylabel(\'stress, \\sigma (MPa)\');

title=title(\'Test Curve for Stress and Strain\');

grid on

set(x0,\'fontsize\',12,\'fontweight\',\'normal\')

set(y0,\'fontsize\',12,\'fontweight\',\'normal\')

set(title,\'fontsize\',12,\'fontweight\',\'normal\')

axis([0 0.08 0 80000])      % Limit

figure(0)

plot(strain_test,stress_test)

x0=xlabel(\'strain, \\epsilon (%)\');

y0=ylabel(\'stress, \\sigma (MPa)\');

title=title(\'Test Curve for Stress and Strain\');

axis([0 0.08 0 80000])    %limits

hold on

plot(0.002,55000,\'d\',\'MarkerFaceColor\',\'b\')

plot(0.02,60000,\'d\',\'MarkerFaceColor\',\'b\')

x=linspace(0,0.01,100);

m=277777.8; %elasticity (y2-y1)/(x2-x1)

y=m*x;

plot((x+0.002),y,\'r\')

%File trapez.m

function int = trapez (x,y)

int=0;

for i=1:length(x)-1

sum=(x(i+1)-x(i))*(y(i+1)+y(i))/2;

int=int+sum;

end
