Compute Strain and Stress in Spherical Coordinates
In theory of elastic media, the stress of the material is a contraction of the rank-4 stiffness tensor (a property of the material) and the rank-2 strain (a property of its deformation). The strain is the symmetrized gradient of the deformation field.
