Two-scale finite element modelling of reinforced concrete structures: Effective response and subscale fracture development
Sign Up to like & getrecommendations! Published in 2018 at "International Journal for Numerical Methods in Engineering"
DOI: 10.1002/nme.5776
Abstract: A two-scale model is derived from a fully resolved model where the response of concrete, steel reinforcement, and bond between them are considered. The pertinent “effective” large-scale problem is derived from selective homogenisation in terms… read more here.

DOI: 10.1002/nme.7151
Abstract: The Dirichlet–Neumann scheme is the most common partitioned algorithm for fluid‐structure interaction (FSI) and offers high flexibility concerning the solvers employed for the two subproblems. Nevertheless, it is not without shortcomings: to begin with, the… read more here.
