- •
We developed a closed-form analytical model to describe the behaviour of chain-link nets.
- •
We modelled the different contact interactions between barrier components.
- •
We developed a Finite Element model taking into account contact conditions realistically.
- •
We provided a description of a rockfall kit able to dissipate 2000 kJ.
- •
We demonstrated the accuracy of the modelling scheme using a real-size field test.
