On the basis of deformation curves from compression tests, particle behaviour under mechanical stress can be approximated with theoretical contact models. Models examined in this study include Walton and Braun, Tomas and Antonyuk, Zener and Thornton. Influence of climatic conditions on particle behaviour as well as hardening effects related to cyclic loading were also considered. Maltodextrin was used as a model substance for primary particles, while irregular shaped titanium dioxide granules were used to study the behaviour of agglomerates. In both cases, results are in good agreement with the established theories. © 2014 Springer-Verlag Berlin Heidelberg.en1434-502120143313326Contact modelsFine particlesMaltodextrinTitanium dioxideIngenieurwissenschaftenJournal Article10.1007/s10035-013-0464-2Other
