The multi-particle finite element method (MPFEM) is used to simulate confined compression of iron ore pellets.The confined compression test consists of a cylindrical steel tube and two compressive platens. The iron ore pellets are confined by the tools and compressed. In the MPFEM model of the test, the iron ore pellets are represented by …

diametrical compression were different from those in the uniaxial unconfined compression. In general, under the same experi ment condition, a compact has much lower tensile strength than compressive strength. The consolidation pressure and particle size had similar effects on the tensile strength to those observed for the compressive strength.
