The figures shown below are geometric surface representations of stress waves propagating through an anisotropic crystal of calcium formate. There are actually three surfaces corresponding to the three eigenvalue solutions to the Christoffel's equation but in this one special case all three surfaces form a continuous connected surface as shown in the top figure. For simiplicity we also show each of the three surfaces (eigenvalues solutions) disconnected from the continuously connected surface. The directions of particle vibrations, [0 degrees (purple)] to 90 degrees (red)], are the eigenvector solutions to the same equation. Here we show a one-to-one mapping of eigenvectors (COLOR) onto their corresponding eigenvalue surfaces (SHAPE). The other two surfaces, innermost and outermost, form a single connected wave surface. The problem here is to observe the complete solution over the entire three-dimenstional region.
