Abstract
The finite element method (FEM) is used for modeling of physical systems in a wide variety of engineering disciplines, including structural dynamics, heat transfer, fluid dynamics, and aerodynamics. In this chapter, the application of FEM in modeling particle systems is introduced, which covers three aspects: (1) modeling of particle–particle interactions, (2) multiple particle finite element modeling (MPFEM), and (3) continuum modeling of powder compaction. A detailed discussion of the constitutive models used for powder compaction is presented, with particular reference to the Drucker–Prager-cap (DPC) model. In addition, methods for determination of material properties for finite element modeling with the DPC model are discussed in detail. Typical applications of FEM in modeling particle systems are illustrated.
