[?] re-opening FICHE 021478 \ SHB en grandes rot. et grandes def.

Hi,

After the refactoring of te0473 ('RIGI_MECA') for SHB elements, I start to have a look at te0477 ('FULL_MECA', 'RIGI_MECA_TANG', 'RAPH_MECA').

I have read some time ago FICHE 021478 that was indicating:

FICHE 021478 wrote:

I am willing to have a look at that topic (not confident I will be able to go much farther than that, but I am curious to know a bit more about how formulating an element in large rotations / large strains).

Please, is it possible to get the file with the total lagrangian formulation of  tangent matrix, as well as the list of test cases that were broken following its activation?

I thank you in advance for your help.
Best regards,

Pierre

Please open an issue in the bitbucket bugtracker. I will complete the description and add files.

Regards.
