A package for evaluating partial and functional derivatives of tensor functions.

Moreover, every objective tensor function depends only on the tensor's invariants.

Computation of the anisotropic cubic elastic Green's tensor function and the elastic energy coefficients of point defects in crystals.

A scalar valued tensor function f that depends merely on the three invariants of a symmetric 3x3 tensor is objective, i.e., independent from rotations of the coordinate system.

Thirty minutes later and a few doors farther along the corridor, Hunt found Marie, Jeff, and two of the students on loan from Princeton, excitedly discussing the set of partial-differential tensor functions being displayed on a large mural graphics screen.
