ISA is a mathematical extension of conventional hypoplastic models for soils to improve simulations of cyclic loading. It can be considered as a reformulation of the conventional intergranular strain theory by Niemunis and Herle (1997).
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 […]
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.
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.
