triaxial compression of sand
In this example, we demonstrate the usage of SimpleSand
model by conducting a triaxial compression simulation.
The model scripts can be downloaded.
The Model
A unit cube defined with C3D8
element is used to represent the specimen.
For the material properties, the following values are used.
Please refer to the corresponding page for explanations.
Loading
The vertical displacement is applied in the same way.
Monotonic
Cyclic
Cyclic displacement load can be applied. It varies cyclicly after the target confinement is achieved.
The load level can be plotted as follows.
Result
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.
