The 2014 Masin hypoplasticity for clays has been implemented in Tochnog Professional under guidance of Dr. David Masin. This implementation includes structure, intergranular strains and visco effects. Extensions to the classical Wolffersdorff hypoplasticity law have been implemented under guidance of Dr. Andrzej Niemunis.

For the Tochnog Professional finite element program see A free trial version up to 100 finite elements, including these new laws, can be downloaded without subscription.

    Hi, professor roddeman,
    Thanks for new hypoplasticity laws in Tochnog Professional. I’d like to know if you could provide the specific program.
