The landslide drag
Shiva P. Pudasaini
Drag is one of the most important energy dissipation mechanisms in nature, including landslides and debris flows. To satisfactorily reproduce laboratory or field data in simulating…
A multi-phase thermo-mechanical model for rock-ice avalanche
Shiva P. Pudasaini
We propose a novel multi-phase thermo-mechanical rock-ice avalanche model. It considers rock, ice and fluid; includes rigorously derived ice melt rate, melting efficiency dependent…
The Frictional Brachistochrone
Shiva P. Pudasaini
Here, I construct an elegant frictional brachistochrone for a mass point motion of a granular material with the Coulomb frictional energy dissipation that inherently includes the e…
Unified Mechanical Erosion Model for Multi-phase Mass Flows
Shiva P. Pudasaini
Erosion poses a great challenge in multi-phase mass flows as it drastically changes flow behavior and deposition pattern by dramatically increasing their masses, adversely affectin…
