Strain Displacement Strain Strain field Strain determination in rocks

Review: 1.What is the orientation relationship between maximum shear stresses and principal stresses? 2. What are trajectories of principal stresses?

(A)General triaxial stress ellipsoid in perspective view. (B)Views normal to each of the principal planes of the ellipsoid. (After W.D. Means,1976)
