Hydro-mechanical analysis of volcanic ash slopes during rainfall

Lyesse Laloui, Alessio Ferrari, John Eichenberger, Chao Li

Rainfall-induced landslides in volcanic ashes represent a major natural hazard in many regions around the world. Due to their loose structure, volcanic ash slopes are prone to rainfall-induced landslides. The paper presents a continuum modelling approach f ...

Wave propagation in periodic buckled beams. Part I: Analytical models and numerical simulations

Alessandro Spadoni, Florian Paul Robert Maurin

Periodic buckled beams possess a geometrically nonlinear, load-deformation relationship and intrinsic length scales such that stable, nonlinear waves are possible. Modeling buckled beams as a chain of masses and nonlinear springs which account for transver ...

Automaton-based stochastic control for navigation of emergency rescuers in buildings

Maryam Kamgarpour, Tony Alan Wood

In this paper we consider the problem of navigating emergency rescuers in buildings. The objective of the rescuer is to reach several critical regions in a building endangered by a spreading hazard and leave safely. We consider stochastic finite state mode ...

Identification of the wave speed and the second viscosity of cavitation flows with 2D RANS computations - Part I

François Avellan, Sébastien Alligné

1D hydro-electric models are useful to predict dynamic behaviour of hydro-power plants. Regarding vortex rope and cavitation surge in Francis turbines, the 1D models require some inputs that can be provided by numerical simulations. In this paper, a 2D cav ...
