Abstract
The behaviour of the semi-solid material is complex to simulate and many approaches
are proposed in the literature to represent it. In this work, different constitutive equations are
studied: the classical Northon-Hoff law, Joly and Merhabian’s one [1] and an innovative
micromechanical model using homogenisation technique [2]. These constitutive equations have
been implemented in the FE code Forge2® to simulate simple forming tests, such as compression
and direct extrusion. The load-displacement curves using the three constitutive equations are
compared in order to estimate their capabilities.
