I am a beginner , My doubt is that I have to Plot Stress Contour of tapered cantilever beam analysed using FEA now I have the value of element Stresses like sigmax , sigmay , tauxy ? How to proceed ?? Please Help..

Here is an example using pcolor
[x,y] = meshgrid(-2:0.1:2);
stress = x.^2+y.^2;
pcolor(x,y,stress)

Sigma_X, Sigma_Y , Tau_XY are the stress components values at each nodes (18) in this case . X and Y axis are the boundary of the problem .

Reshape your data to create a matrix
stress = reshape(Sigma_X,6,3);
And use pcolor
[x,y] = meshgrid(1:3,1:6);
Sigma_X = 1.0e+03 * [-4299.57587958638 -3965.44553517593 -3204.63754334495 -2292.69609509300 -1230.97384069952 -654.515387137445 7.73070496506989e-12 8.64019966684282e-12 1.11413100967184e-11 1.02318153949454e-11 2.84217094304040e-12 -1.93267624126747e-12 4299.57587958640 3965.44553517595 3204.63754334497 2292.69609509302 1230.97384069952 654.515387137441];
