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 […]
On behalf of the team of developers I am happy to announce that, after more than four years of development and testing, ExCalibre has just been launched. ExCalibre is a […]
A PhD-level course on hypoplastic constitutive modelling intended for both academia and practitioners.
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.
Download package of barodesy model. Contains ABAQUS umat (source code), Plaxis UDSM (dll files only, not source code), package documentation, related journal publications, Abaqus and Plaxis examples.
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.
Clay hypoplasticity is an advanced incrementally non-linear constitutive model based on critical state soil mechanics developed specifically for simulation of fine-grained materials.
Based on some requests, I share here two presentations on hypoplasticity applications. One is related to simulation of various boundary value problems, the other focuses on simulation of cyclic and […]
The Tochnog Professional finite element program is now available as free version with 100 elements. It can be downloaded without registration from http://www.feat.nl. Several commercial and free pre- and postprocessors […]
