Liu, D. (author), van den Boom, S.J. (author), Simone, A. (author), Aragon, A.M. (author)We propose an enriched finite element formulation to address the computational modeling of contact problems and the coupling of non-conforming discretizations in the small deformation setting. The displacement field is augmented by enriched terms that are associated with generalized degrees of freedom collocated along non-conforming...journal article 2022
