High performance hybrid FEM/DEM simulation tool for numerical analysis of historical structures

The current paper aims at presenting the various aspects of a modeling and simulation framework dedicated to the study of historical structures considered as complex mechanical systems with interactions (contact, friction, cohesion, etc) and multi-physics couplings (thermal effects, diffusion, etc). Based on the proposed framework a simulation tool has been developed, with a complete strategy (pre-processing, simulation, post-processing), making possible to deal efficiently with the numerical modeling of those structures; it is available as an open-source software: LMGC90 [4].
