    • 3D regularized µ(I)-rheology for granular flows simulation 

      Franci, Alessandro; Cremonesi, Massimiliano (2019-02)
      Article
      Open Access
      This paper proposes two regularized models of the µ(I)-rheology and shows their application to the numerical simulation of 3D dense granular flows. The proposed regularizations are inspired by the Papanastasiou and ...
    • 3D simulation of Vajont disaster. Part 1: numerical formulation and validation 

      Franci, Alessandro; Cremonesi, Massimiliano; Perego, Umberto; Crosta, Giovanni Battista; Oñate Ibáñez de Navarra, Eugenio (2020-12)
      Article
      Restricted access - publisher's policy
      This work presents a numerical method for the simulation of landslides generated impulse waves and its application to the historical Vajont case study. The computational tool is based on the Particle Finite Element Method ...
    • 3D simulation of Vajont disaster. Part 2: multi-failure scenarios 

      Franci, Alessandro; Cremonesi, Massimiliano; Perego, Umberto; Oñate Ibáñez de Navarra, Eugenio; Crosta, Giovanni Battista (2020-12)
      Article
      Restricted access - publisher's policy
      Prediction of multi-hazard slope stability events requires an informed and judicious choice of the possible scenarios. An incorrect definition of landslide conditions in terms of expected failure volume, material behavior, ...
    • A fully explicit fluid-structure interaction approach based on PFEM and FEM 

      Meduri, Simone; Cremonesi, Massimiliano; Perego, Umberto (CIMNE, 2017)
      Conference report
      Open Access
      Partitioned approaches for the solution of Fluid-Structure Interaction (FSI) problems are particularly interesting because, among other aspects, they allow for the reuse of existing software. In this work, we propose a ...
    • A Lagrangian nodal integration method for free-surface fluid flows 

      Franci, Alessandro; Cremonesi, Massimiliano; Perego, Umberto; Oñate Ibáñez de Navarra, Eugenio (2020-04)
      Article
      Restricted access - publisher's policy
      We present a Lagrangian nodal integration method for the simulation of Newtonian and non-Newtonian free-surface fluid flows. The proposed nodal Lagrangian method uses a finite element mesh to discretize the computational ...
    • A PFEM approach to the simulation of landslide generated water-waves 

      Cremonesi, Massimiliano; Di Prisco, Claudio; Perego, Umberto (CIMNE, 2013)
      Conference report
      Open Access
      A Particle Finite Element Method is here applied to the simulation of landslide-water interaction. An elastic-visco-plastic non-Newtonian, Bingham-like constitutive model has been used to describe the landslide material. ...
    • A state of the art review of the Particle Finite Element Method (PFEM) 

      Cremonesi, Massimiliano; Franci, Alessandro; Idelsohn Barg, Sergio Rodolfo; Oñate Ibáñez de Navarra, Eugenio (2020-11)
      Article
      Open Access
      The particle finite element method (PFEM) is a powerful and robust numerical tool for the simulation of multi-physics problems in evolving domains. The PFEM exploits the Lagrangian framework to automatically identify and ...
    • On the effect of standard PFEM remeshing on volume conservation in free-surface fluid flow problems 

      Franci, Alessandro; Cremonesi, Massimiliano (Springer, 2017-07)
      Article
      Open Access
      The aim of this work is to analyze the remeshing procedure used in the particle finite element method (PFEM) and to investigate how this operation may affect the numerical results. The PFEM remeshing algorithm combines the ...
