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 is included as an example in the following products:Geomechanics Module
however additional products may be needed to reproduce it. This example may be created and run using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license.
