A family of constitutive models implemented in PLAXIS to simulate cemented mine backfill

Nicolás A. Labanda is a Consultant in SRK´s Buenos Aires office, with eight years of industry and academic experience. He has experience in design of concrete and steel structures for cement industry according to Argentinian, USA and Peruvian codes and standards. His experience includes collapse analysis of structures manufactured with plain and steel fiber reinforced concrete under blast loads, using the finite element method. The activities as SRK consultant includes numerical modeling in two and three dimensions of tunnels for the Buenos Aires metro (TBM, NATM, C&C), design of geotechnical structures and the development of mathematical models and computational codes for engineering applications. As part of his research activity, he has published in conferences and international journals in subjects concerning numerical and constitutive modeling, fracture and damage mechanics and structural analysis. He also collaborates as a teacher at the University of Buenos Aires, Argentina.

Osvaldo Nicolás Ledesma is a Senior Consultant at SRK´s Buenos Aires office, with experience in the design of foundations, excavations, tunnels, embankments and retaining structures for infrastructure and mining projects in Argentina, Peru, Paraguay, Uruguay, Canada and Papua New Guinea.  He has advanced knowledge of numerical methods for geotechnical structure design as well as experience in geotechnical field and laboratory testing. Osvaldo is currently pursuing a PhD in numerical modelling of soils in unsaturated conditions and serves as Assistant Professor of Soil Mechanics and Geology at the University of Buenos Aires.
