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).
Download package of ISA cyclic hypoplasticity model. Contains umats and example Abaqus input files. Umats (ISA+sand hypoplasticity) allow to switch between ISA and classical intergranular strain concept.
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 […]
