Abstract: | The quasi-static compressive mechanical behavior and deformation mechanism of closed-cell magnesium foams were studied, and
the effects of the density of magnesium foams on the compressive and energy absorption properties were also discussed. The
results show that the compressive process of closed-cell magnesium foams is characterized by three deformation stages: linear
elastic stage, collapsing stage and densification stage. At the linear elastic stage, the peak compressive strength (σ
0) and Young’s modulus (E
0) increase as the density increases. Magnesium foams can absorb energy at the collapsing stage. In a certain strain range,
the energy absorption capacity also increases as the density of magnesium foams increases. |
