Use of machine learning for unraveling hidden correlations between particle size distributions and the mechanical behavior of granular materials.

Acta Geotech 2022 7;17(4):1443-1461. Epub 2021 Dec 7.

Institute of Mathematics, École Polytechnique Fédérale de Lausanne, 1015 Lausanne, Switzerland.

A data-driven framework was used to predict the macroscopic mechanical behavior of dense packings of polydisperse granular materials. The discrete element method, DEM, was used to generate 92,378 sphere packings that covered many different kinds of particle size distributions, PSD, lying within 2 particle sizes. These packings were subjected to triaxial compression and the corresponding stress-strain curves were fitted to Duncan-Chang hyperbolic models. Read More

Second-order work in barodesy.

Acta Geotech 2019 18;14(5):1483-1493. Epub 2018 Dec 18.

Division of Geotechnical and Tunnel Engineering, University of Innsbruck, Technikerstr. 13, 6020 Innsbruck, Austria.

Second-order work analyses, based on elasto-plastic models, have been frequently carried out leading to the result that failure may occur the limit yield condition is encountered. In this article, second-order work investigations are carried out with barodesy regarding standard element tests and finite element applications. In barodesy, it was shown-like in hypoplasticity and elasto-plasticity-that second-order work may vanish at stress states inside the critical limit surface. Read More
