Triaxial Test

Application 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 application was built using the following:

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product's capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
