Previous work within mechanics of pellets performed by the research group has dealt with describing the mechanical stress- and strain-field of pellets in a silo or other storage or transportation systems. In this work numerical methods suited for several applications regarding granular material are developed and evaluated. The Smoothed Particle Hydrodynamic (SPH) method and Particle Finite Element Method (PFEM) are used along with the more traditional finite element method (FEM). The specific goal of the project is to predict forces, stresses and critical loading in mining, milling and silo applications. A secondary goal of the project is to strengthen the co-operation between the world-leading Centre for Numerical Methods in Engineering (CIMNE) at Technical University of Catalonia, Barcelona and Luleå University of Technology. CIMNE has a well established position in the field of modelling of fluids and granular material and its interaction with solid material. They are the founders and developer of the PFEM method. For LTU and LKAB cooperation would strengthen the competence in numerical modelling of granular processes and also give possibility to interact with a world wide network of researchers in numerical modelling.
