In this example, we demonstrate the usage of model by conducting a triaxial compression simulation.
The model scripts can be .
A unit cube defined with element is used to represent the specimen.
For the material properties, the following values are used.
Please refer to the corresponding page for explanations.
The confinement is applied to achieve a confinement stress of .
In this case, a displacement of would do the job.
The vertical displacement is applied in the same way.
Cyclic displacement load can be applied. It varies cyclicly after the target confinement is achieved.
The load level can be plotted as follows.
The - response is shown as follows. As a linear relationship is assumed for elastic part, linear line segments are expected within the yield surface.
The SimpleSand model is a very simple model for sand to showcase the concept of bounding surface.
For more advanced response, other models shall be used.
