Consider an orthotropic material with the stiffness matrix given by
Â

Find:
1. The stresses in the principal directions of symmetry if the strains in the principal directions of symmetry at a point in the material are ε1 = 1 μm/m, ε2 = 3 μm/m, ε3 = 2 μm/m; γ23 = 0, γ31 = 5 μm/ m, γ12 = 6 μm/m
2. The compliance matrix [S]
3. The engineering constants E1, E2, E3, ν12, ν23, ν31, G12, G23, G31
4. The strain energy per unit volume at the point where strains are given in part (1.)
