Abstract: The quasi-static indentation response process of Al foam panels under a spherical end cylindrical indenter was simulated by MSC/Marc finite element software to study the displacement and stress field distribution. And the simulated results were compared with the experimental results. Results show that the displacement field and stress field distributed in the region of Al foam corresponding to indenter diameter scope. The distribution range extended outwardly around the indentation with the increase of the indentation depth. The simulation results were coincided with the experimental results in deformation zone shape of Al foam. The simulation result of indentation can be used to greatly explain the deformation mechanism of Al foam under the spherical end cylindrical indenter.
