Incremental Driver

A dedicated special purpose incremental driver has been developed which is able to calculate the results of homogeneous experiments. Both displacement controlled and force controlled experiments can be performed. The program is fully parallised; it can calculate fast large amounts of experiments.

The following experiments can be used:


The following material laws can be used:
The following deformation models can be used:
Results are printed for:
Examples are shown below. We use the geotechnics convection in which compression is positive and extension is negative. The corresponding input files can be found in your distribution in the directory test/incremental_driver.
