EnglishTo explore the possibility of proper modeling, the dissipation in specimens made of concrete, a reduced two-degrees-of-freedom model, obtained from a nonlinear micromorphic model is employed in the case of cyclic mono-axial compressive tests. This model assumes that the nonlinear nature of the mechanical response arises from the microstructure and specifically from the micro-cracks regularly present in the cement matrix. The dissipation, therefore, is introduced as Coulomb-type friction associated with the relative motion of the faces of the micro-cracks. Numerical simulations showing that the proposed model is fitting to describe some of the known responses of the concrete are performed.
