Abstract
Geomaterials are modelled as deforming multiphase porous media with a solid, liquid and/or gaseous phase. The models differ according to the mass transfer mechanism taking place at high, medium or low water content. The Finite Element Method is used for the discretization in space of the governing equations.
Sommario
Geomateriali, cioè terre, rocce, calcestruzzi, sono modellati come mezzi porosi multifase, deformabili, composti quindi da una fase solida, da une fase liquida e/o una gassosa. I modelli relativi differiscono secondo il meccanismo di trasporto di massa che prevale ad alto, medio o basso contenuto d'acqua. Il metodo degli elementi finiti è utilizzato per la discretizzazione spaziale e temporale delle equazioni differenziali che governano il problema.
