2 Education Diploma di Liceo Scientifico. Istitutuzione culturale don C. Gnocchi Carate Brianza (MI ) Sep – Sep. 2008, POLITECNICO DI MILANO Bachelor of Science in Civil Engineer (Politecnico di Milano) Thesis: VALUTAZIONE DELLA SICUREZZA DI UNA MINIERA DI GESSO ABBANDONATA MEDIANTE ANALISI TRIDIMENSIONALE Supervisor: Prof. Roberto Nova Assistant supervisor: Ing. Riccardo Castellanza

3 VALUTAZIONE DELLA SICUREZZA DI UNA MINIERA DI GESSO ABBANDONATA MEDIANTE ANALISI TRIDIMENSIONALE FEM CODE MIDAS GTS

4 Education Apr – Mar. 2011, OXFORD UNIVERSITY Thesis: DEM INVESTIGATION ON THE INITIATION AND PROPAGATION OF COMPACTION BANDS IN POROUS ROCKS Supervisor: Prof. Claudio di Prisco Assistant supervisor: Ing. Stefano Utili Sep – March 2011, POLITECNICO DI MILANO Master of Science in Civil Engineer – Geotechnics 110/110 e Lode

5 Compaction bands Navajo Sandstone: Mollema e Antonellini 1996 Polycarbonate honeycomb: Papka e Kyriakides 1999 Soft porous rocks: Castellanza, Gerolymatou, e Nova 2009

6 DEM simulation of compaction bands Elasto-plastic parallel bond model Elasto-brittle and elasto-damage parallel bond model

7 Papers A numerical and theoretical investigation of compaction band propagation in cemented highly porous granular materials Submitted to: International Journal for Numerical and Analytical Methods in Geomechanics -Effects of damping -Effect of the bond model (mechanical degradation law) -Effect of the size of macro-voids

8 Feature work Numerical modeling of flow-like landslides (and debris flow) in granular masses rheological model capable of deal with the phase transition of granular materials from a solid-like to a fluid-like state and vice versa (D. Berzi, C. G. di Prisco and D. Vescovi (2011)) modeling of a granular, heterogeneous and multiphase material Evolution process from slide to flow: transition phase between the solid (inception of instability) and the fluidized states (runout) - dry granular mass (bi-phase) - removal of the hypothesis of incompressibility and the introduction of the coupling between deviatoric and volumetric strains -PFEM (Cremonesi et al., 2011) -SPH (Pastor et al., 2008, 2009). large displacements continuum mechanics
