Elastic deformationThe strain tensor ε of a crystal is related to the stress tensor σ by the stiffness tensor, εij = sijklσkl (a) A tensile stress is applied in the x-direction and shear stress is applied in the y-direction to the z plane. What is the resulting strain? (There are in general 18 terms.) (b) How many terms are there if the crystal is cubic? |
