- Description
- This paper presents a discrete framework for the modelling of composite structures for rockfall protection. The model is applied to analyse the dynamic response of a cylindrical damping module upon impact of a boulder. The damping module consists of a cylindrical wire mesh, two steel rings, a boundary rope, a geotextile lining and a granular filling material. The chain-link wire mesh, the steel rings and the boundary rope are represented with deformable cylinder elements. The geotextile lining is incorporated into the openings of the wire mesh by using deformable facets. The filling material is represented using spherical particles.
