I have determined that d3 is not a departure from the "s" unit vector of the traditional kenematicians (everyone but Antman). d3 and "s" are identical.
The big question remaining---which Antman does not address at all---is how do we calculate shear deformation? D1s(r(s,t)---d3---is the slope in global coordinates and D2s(r(s,t)) is "u"; there is no method to calculate shear deformation.

I have settled in to the lab and I have made some progress on the Antman dynamic equations in chapter 8. I am stiff confused about the tensor "J" though.

I have restated my study of Antman; in particulat, chapter 8. I am planning to work through all of the derivations over the next week ( or two ).
