TOCHNOG PROFESSIONAL

TOCHNOG FREE VERSION

A professional tochnog version is distributed by FEAT. Please visit http://www.feat.nl.

Presently the Matsuoka-Nakai plasticity model is being implemented by Ivo Herle of the Czech Academy of Sciences, and by Dennis Roddeman of FEAT. This plasticity model has some better experimental and numerical properties than the classical mohr-coulomb yield surface. To be expected near the end of 2000.

The department of foundation engineering and tunneling of Ed. Zueblin A.G., Germany, sponsors the integration of hypoplasticity in Tochnog. A state-of-the-art version (automatic time-substepping, integranular strains, pressure dependent porosity, cohesion, etc.) will become available later this year. This extends the library of granular material models already present (like the classical elasto-plastic models such as Mohr-Coulomb, Di-Prisco, etc.).

Now results files for IBM’s open sourced data explorer can be generated. Look in http://www.opendx.org for the data explorer visualisation program. Presently generic visualisation of data explorer can be used for Tochnog results. To be expected are Tochnog specific visualisation networks in data explorer.
