Triaxial Test

Model ID: 9702


The triaxial test is one of the most common tests used in laboratory soil testing. The soil sample is normally placed inside a rubber membrane and then compressed maintaining a radial pressure.

In this model, a vertical displacement and a confinement pressure are applied on the sample and the static response and the collapse load for various confinement pressures are studied. The material is modeled with the soil plasticity feature, and the Drucker-Prager criterion. The analysis can be simplified by considering the intrinsic axial symmetry of the model.

This model was built using the following:
