Hi,
I am wanting to use Maxima to do some material parameter estimation
which involves evaluating the finite elasticity stress and strain
tensors. One way to do this is to represent the relevant tensors as
matrices but since Maxima can deal with tensors I am wondering if there
would be any advantage in using the tensor functions instead?
However I'm still learning about all this and I can't figure out from
the available demos how to do it.
In an old newsgroup post some Macsyma demos on elasticity were
mentioned, and I thought these might be a good place to start:

> DEMO(STRAIN1); Derive strain tensor in elasticity of solids
> DEMO(STRESS1); Derive stress tensor in elasticity of solids
> DEMO(TENS_PDE); Generate tensor finite difference equations.
but these appear not be included in Maxima.
Does anyone know if they are available and from where?
Also are there any examples showing how to use tensors to get a
numerical answer or is this simply a matter of assigning values to the
variables as for any other problem?
