Discrete element modeling of masonry structures
There is another micro modeling approach namely the discrete element method (DEM) that should provide an adequate representation of masonry depending on the number of contacts and complexity of the corresponding model. The nature of masonry is particularly suitable for this numerical modeling initially developed by Cundall (1971).
