Plane strain compression tests carried out on samples of dense siliceous sand have been simulated numerically by adopting a finite element approach that accounts for strain softening effects. Both standard Drucker-Prager yield condition, with a non-associated flow rule, and the Hierarchical Single Surface (HiSS) constitutive model were adopted in the calculations. The comparison between the experimental data and the results of analyses permits to draw some conclusions on capability of the mentioned constitutive laws in modeling the strain softening behaviour.

Abstract
Plane strain compression tests carried out on samples of dense siliceous sand have been simulated numerically by adopting a finite element approach that accounts for strain softening effects. Both standard Drucker-Prager yield condition, with a non-associated flow rule, and the Hierarchical Single Surface (HiSS) constitutive model were adopted in the calculations. The comparison between the experimental data and the results of analyses permits to draw some conclusions on capability of the mentioned constitutive laws in modeling the strain softening behaviour.File in questo prodotto:
