Title
Tochnog Driver
Description
[Official Distributor Text]
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.

Available Constitutive Models
Clay hypoplasticity is an advanced incrementally non-linear constitutive model based on critical state soil mechanics developed specifically for simulation of fine-grained materials.
SANISAND is an advanced elasto-plastic model based on a concept of rotational hardening incorporating the effects of fabric-dilatancy.
Sand hypoplastic model is an advanced incrementally non-linear constitutive model for sand, an outcome of an extensive research at Karlsruhe University in 1990's.
Barodesy is a constitutive model for granular media and does not use standard notations of elasto-plasticity, e.g. yield function, flow rule or plastic potential.
A high-cycle explicit model for the accumulation of strain in sand due to small cyclic loading. The dependence of the accumulation rate on stress, void ratio, cyclic history and the type of loading is considered. In particular, the ovality and the polarization of the strain path during a cycle are taken into account.
