Dear all, I’m using the UMAT file in which the hypoplastic model for thermal cycles is implemented. In the Abaqus input file I have added the two lines necessary to […]
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.
Model to simulate the cumulative feature of volumetric contraction of fine-grained soil subjected to thermal cycles. A thermal stabilization line is introduced to control the stabilized volumetric contraction under thermal cycles.
