Abstract. Virtual tests enable the expansion of the knowledge base accessible by direct experimentation. In particular, the role of microstructure on damage can be investigated using unit-cell models for porous materials. Additionally, it is of great interest to assess the role of the loading history on the response. In this paper, we present a dedicated user-defined element (U.E.L.) that was developed and implemented in the finite element (F.E.) code, ABAQUS. Verification of the capabilities of the U.E.L. is provided. The simulation results presented provide insights into the effect of J3 on the mechanical response and porosity evolution.
