Spark Plasma Sintering (SPS) is a promising rapid consolidation technique that allows a better understanding and manipulation of sintering kinetics and therefore makes it possible to obtain polycrystalline materials (ceramic or metallic) with tailored microstructures. A numerical simulation of the electrical, thermal and mechanical coupling during SPS is performed. Equations for conservation for energy, electrical charge and mechanical equilibrium are solved simultaneously. The strong coupling in term of temperature, on the thermal conductivity and electrical resistivity are considered.
