Spark Plasma Sintering belongs to a class of sintering techniques that employs electric current to assist compaction. The present paper addresses the numerical modelling of the coupled electrical and thermal problems. Numerical simulations are carried out for two samples (TiAl and alumina). The distribution of electric current and temperature are shown in the specimen as well as in the tooling, providing a better understanding of the SPS.
