The new RAMMS::ROCKFALL model (not yet released!) employs a hybrid approach combining rigid body mechanics with scarring mechanisms for soft compactable soils. It permits an explicit description of arbitrary three dimensional polyhedral bodies, including natural rock-shapes. Introducing real rock-shapes into rockfall modelling enables a better inclusion of the natural variability of rock-shapes and sizes generated from differing geological settings. With this we come closer to modelling the true nature of rockfall runout behaviour, integrating rock-shape and the release kinematics characteristic of site specific rockfall hazards.

The theoretical framework of the new RAMMS::ROCKFALL model is described in full detail in  Lu et al, 2019Leine et al, 2014, and Leine et al., 2021. Below, the most important features are highlighted.


Non-Smooth mechanics framework

Energy dissipation

The new energy dissipation model is based on the work energy theroem for rigid bodies impacting compactable soft soils.



Dam Interaction

Calculation of impact forces, penetration depth and trajectories after a possible rebound.
