Dear Liran,
I think your point is a very important one. It is not so easy to connect geometry to kinematics and finally dynamics.
the closest to what you are looking for is the book by Fletcher and Pollard:
https://pangea.stanford.edu/projects/structural_geology/chapters/index.html
You may also want to check out online lectures and movies of experiments and models explaining some of these problems:

Good luck
kind regards,

Dear Liran,
I like your approach. I could offer you incremental displacement fields calculated from optical recording of analogue tectonic experiments plus the images, if that is of any use? Examples in Leever et al., 2011 or alternatively Adam et al., 2005, Schrank et al., 2008. Send me a message if you are interested.
Otherwise, I suppose you know the text book by Allmendinger Cardozo and Fisher, or the one by Fossen (with supplementary material here http://folk.uib.no/nglhe/StructuralGeoBook.html). You may find something useful there or in the authors' work.
cheers and good luck,
Karen

In the first several weeks I teach basic intro to continuum mechanics where stress and strain are presented from the tensorial perspective. In the second part, the focus is more on structures in the field. So far I didn’t find a way to tie the two parts in a quantitative way. I.e. to find field (or even theoretical) examples that can be analysed using the stress/strain/deformation gradient tensors, which are simple enough for an undergrad course and still cannot be more easily solved using a Mohr circle approach.
