Hi,

I was verifying the contact law before committing (rev 1972).   The result matches well with the one with Plassiard et al. (2009).   Currently it uses incremental shearForce, rather than incremental displacement.  It takes awhile to update the code from an old version.  It works ok.

Cheers,

CWBoon
