Multiscale analysis of masonry walls

Assets

  • Multi-scale modeling of masonry walls
  • Hybrid FEM-DEM solver
  • Nonlinear static and dynamic analyses
  • Multi-platform
  • Integrated CAD

SMARTwall is a desktop application developed since 2007 for the nonlinear static and dynamic analysis of masonry walls featuring our state-of-the-art hybrid FEM-DEM solver, capable of multi-scale material modeling and a user-friendly graphical interface with integrated CAD (since 2011). Distinct element modelling (DEM) is an efficient choice for structures like cathedrals and for limit analysis. Our multiscale approach based on a continuum with DEM mesosctructure allows for an accurate modelling of masonry mechanics and efficient computations. Finally, the hybrid approach allows us to treat as an FE-discretized multi-scale continuum the region of the structures where a periodic mesostructure is present (where results are presented in terms of Cauchy stress), while DEM is used for the regions where the mesostructure is unique like in arches (where results are presented in terms of thrust lines). The multi-platform GUI features a smart CAD, multiple languages and unit systems, automatic mesh generation and a graphical post-processor.
