“…To evaluate the energy absorption performance of the aluminum foam, they also proposed the energy absorption efficiency and the ideal energy absorption efficiency. The energy absorption efficiency is broadly used in the study of the energy absorption performance of various aluminum foams [16][17][18][19].…”

In order to explore the evolution of physical and mechanical properties and acoustic emission (AE) characteristics of aluminum foam under fatigue and quasi-static compression from a microscopic point of view, the AE monitoring technology was used to analyze the deformation, hardening, and energy absorption characteristics of open-cell aluminum foam under quasi-static compression at different rates (2, 10 and 50 mm/min) and fatigue loading tests with different peak stress ratios k (k = maximum stress/yield stress) by means of MTS fatigue testing machine and CCD camera. The results indicated that under different compression rates, the AE ring down count had the same trend as the engineering stress–strain response of the specimens, the AE ring down count rate at the plastic deformation stage showed the same performance as the work hardening rate, and the AE energy absorption efficiency corresponded well to the experimental results. The specimen entered the densification stage with the stability of AE count and the decrease in energy absorption efficiency. During the fatigue tests of different k values, the change trend of strain was consistent with the response of acoustic emission characteristic parameters, and the fatigue compression damage caused by the deformation process of the specimen can be monitored by the change in AE characteristics. The AE characteristics can dynamically monitor the compression process and provide a new research method and idea for the study of mechanical properties of aluminum foam.

“…The results reveal that it is possible to produce aluminum metal foam without a stabilizing agent with coequal physical and mechanical properties. D. Yang et al [12] prepared ex-situ aluminum cellular structurefilled tubes. The samples were tested for quasi-static compression and energy absorption behavior, and it was reported that the filling ratio and positioning of the cellular structure inside the tube play a crucial role in tailoring the foam's compression and energy absorption behavior.…”

Metal foams are a unique material that is gaining attraction in various industries due to their multifunctional features. This work focuses on understanding the tribological behavior of aluminum-based close-cell metal foams where Zn is added as reinforcement in different weight percentages (0, 0.5, and 1 wt.%). Dry sliding wear tests are performed at varying loads (5, 10, 15, and 20 N) and sliding distances (1000, 2000, 3000, and 4000 m). During the tests, two limiting conditions are considered: the sliding speed of the rotating disc and its track diameter, which are set at 2.5 m s −1 and 10 cm, respectively. The result reveals that specific wear rate (SWR) is a function of porosity, which increases with an increase in porosity. It was discovered that wear occurs when asperities of varying hardness come into contact at lower stress levels. However, at greater load values, the mechanism shifts from abrasion to plastic flow and delamination. K e y w o r d s : metal foam, specific wear rate (SWR), SEM

“…Recently, some effective structures have been proposed and designed to increase the specific strength and energy absorption of lattice structures and foam structures [24][25][26][27]. Metallic and polymeric foams are used as filling material to improve the mechanical performance of sandwich structures with lattice cores and have proved to be effective [25][26][27][28].…”

The design of lightweight sandwich structures with high specific strength and energy absorption capability is valuable for weight sensitive applications. A novel all-metallic foam-filled Y-shape cored sandwich panel was designed and fabricated by using aluminum foam as filling material to prevent core member buckling. Experimental and numerical investigation of out-of-plane compressive loading was carried out on aluminum foam-filled Y-shape sandwich panels to study their compressive properties as well as on empty panels for comparison. The results show that due to aluminum foam filling, the specific structural stiffness, strength, and energy absorption of the Y-shape cored sandwich panel increased noticeably. For the foam-filled panel, aluminum foam can supply sufficient lateral support to the corrugated core and vertical leg of the Y-shaped core and causes a much more complicated deformation mode, which cannot occur in the empty panel. The complicated deformation mode leads to an obvious coupling effect, with the stress–strain curve of the foam-filled panel much higher than those of the empty panel and aluminum foam, which were tested separately. Metallic foam filling is an effective method to increase the specific strength and energy absorption of sandwich structures with lattice cores, making it competitive in load carrying and energy absorption applications.
