Abstract
ABSTRACT This paper focuses on the modelling of an innovative rockfall protection barrier built with cell assembly. The mechanical response of geo-composite structures subjected to an impact is analyzed. The modelling of the structure is based on a multi-scale approach. First the constitutive behaviour of a single cell is investigated. Different kinds of loading paths are considered (quasi-static and dynamical loading conditions). Then, the entire structure is considered. For this purpose each cell is described by a single node and the interaction between adjoining nodes is described by means of the constitutive model developed for each single cell. Preliminary structure impact simulations are finally commented.
