Andrew, as a postscript to my previous mail: I don't know what you use to generate output, but VTK has the ability to plot tensor-valued data. If you wanted to do that, you'd probably also have to extend the DataComponentInterpretation mechanism that tells DataOut which variables are scalars, vectors, or in your case tensors. That is independent of the extractors, however, and you'll be able to implement them separately if you wanted to do that.
As for tensors in general: Are your stress tensors not symmetric? If they are, do you implement them as 6-component (in 3d) objects, or as full unsymmetric 9-component object?
