The compression behavior of two different simulation models for the closed-cell Al foam-filled tube established by Digimat and ABAQUS
Abstract
In this work, two types of models for a closed-cell Al foam with 80% porosity were established by Digimat and ABAQUS. The compression characteristics of the Al foam-filled stainless steel tube structure with both Al foam models were simulated and compared in combination with experiments. The results showed that Al foam-filled tubes presented higher peak compressive force compared with unfilled stainless steel tube. Compared with the crushable Al Foam model established by ABAQUS, the Digimat model could intuitively observe the plastic deformation in the cells of the Al foam-filled structure. However, the simulated results derived from Digimat software were slightly different from the experimental result. In general, the crushable-foam model embedded in ABAQUS can better match the experimental results from a macro perspective.
