I am happy to announce that our pre-print paper, “Multi-objective analysis of the Sand Hypoplasticity model calibration”, is available on researchgate (https://www.researchgate.net/publication/369199567_Multi-objective_analysis_of_the_Sand_Hypoplasticity_model_calibration) and Axive (https://doi.org/10.48550/arXiv.2303.07234). In this work, we study […]

MATLAB Code for Bounding Surface Plasticity Model

Views 3,448
Dear Altruists, I just wanted to learn the bounding surface plasticity theory with coding. Does anyone have any code (written in MATLAB) for the Bounding Surface Plasticity model? Could you […]
Dear all, I am currently writing a proposal for a (small & hopefully nice) eLearning project: Within the project, I would like to create animations related to constitutive modelling. I […]
Sand Hypoplasticity calibration

Good evening, everyone. I find it difficult to apply equations (13) and (14) of Herle’s publication “Determination of parameters of a hypoplastic constitutive model from properties of grain assemblies”. As […]

Hi everyone I am writing a code for a model in the UDSM format for Plaxis. I already have the “*.dll” files, but when I run the soil test I […]
Constitutive Model for clayey sand Soils Considering the Effect of Intergranular Physicochemical Forces

Views 3,486
Hi all, I’m doing some experimental work to investigate the salinity effect on clayey sand behaviour. Is there any constitutive model considering the physicochemical forces for such materials? Regards, Mehdi
