Parameter identification for soil simulation based on the discrete element method and application to small scale shallow penetration tests Jahnke, Jonathan Steidel, Stefan Burger, Michael Papamichael, Salomi Becker, Andreas Vrettos, Christos Àrees temàtiques de la UPC::Matemàtiques i estadística::Anàlisi numèrica::Mètodes en elements finits Finite element method Computational methods in mechanics Particle methods (Numerical analysis) Granular Materials, Discrete Element Method, Parametrization, Triaxial Compression Test, Shallow Penetration Test Elements finits, Mètode dels The Discrete Element Method (DEM) is well-established and widely used in soil-tool interaction related applications. As for all simulation tools, a proper calibration of the model parameters is crucial. In this contribution, we present the parametrization procedure of the DEM software GRAnular Physics Engine (GRAPE), developed and implemented at Fraunhofer ITWM, and attempt to use two parametrized soil samples for the simulation of small scale shallow penetration tests. The results are compared to laboratory measurements. 2019 Conference report 978-84-121101-1-1 https://hdl.handle.net/2117/186586 eng Open Access 11 p. application/pdf CIMNE
