Consider the following stress tensor: 5 0 0 T= 0 -6 -12 0 -12 1 First, draw this stress state on a representative 3D stress element. Next, find the eigenvalues (principal stresses) of this tensor by finding the determinate of [T-AI]. Next, find the three principal vectors, n(¹), n(²), and n(³) corresponding to each principal stress using the reduced row echelon method on the augmented matrix.
