“…Foams are bio-inspired, cellular and lightweight materials that offer a unique energy absorption capacity e.g., as crash energy absorber [1][2][3][4] or also as catalyst supports [5]. Hybrid foams belong to the group of composite foams and are characterized by a combination of different materials.…”

Nickel(Ni)/aluminium(Al) hybrid foams are Al base foams coated with Ni by electrodeposition. Hybrid foams offer an enhanced energy absorption capacity. To ensure a good adhering Ni coating, necessary for a shear resistant interface, the influence of a chemical pre-treatment of the base foam was investigated by a combination of an interface morphology analysis by focused ion beam (FIB) tomography and in situ mechanical testing. The critical energy for interfacial decohesion from these microbending fracture tests in the scanning electron microscope (SEM) were contrasted to and the results validated by depth-resolved measurements of the evolving stresses in the Ni coating during three-point bending tests at the energy-dispersive diffraction (EDDI) beamline at the synchrotron BESSY II. Such a multi-method assessment of the interface decohesion resistance with respect to the interface morphology provides a reliable investigation strategy for further improvement of the interface morphology.

“…The ability to absorb energy by aluminium foam material can be determined by the area under the curve in a stress-strain diagram; the wider the plateau region, the higher the energy absorption. In addition, it is important to understand low and high strain rate behavior for assessment of enhanced energy absorption and crashworthiness behavior [31][32][33][34][35][36][37]. Myers et al studied about material which strongly depended on the chemical composition of metal matrix composite (MMC) and also disclosed heat treatment conditions, and explored stiffness and fracture mechanism under quasi-static loading and high strain rate [35].…”

“…The foaming agent and the graphene sheets were cryomilled before dispersing into the melt. The graphene sheets were detached in the melt and found along the side of the walls and stabilized the foam structure [31][32][33][34]50]. It is more beneficial to use fewer foam materials in escalated dynamic loads condition where energy absorption is high.…”

The present work was addressed to the closed-cell aluminum (Al)-silicon carbide (SiC) particles (15 wt.%) with graphene (0.5 wt.%) reinforced hybrid composite foam, which was produced through the melt route process. Under the strain rates ranging from 500 s −1 to 2760 s −1 , the compression deformation behavior of hybrid composite foam was executed. The compression results disclosed that plateau stress along with energy absorption of produced hybrid composite foam are heightened with strain rates and is also discovered to be responsive to the relative density under the confront domain of experiments. Analysis of Variance was deployed for optimizing parameters such as strain rates, mass, density, relative density, and pore size. Furthermore, the contribution of each optimized parameters on plateau stress and energy absorption were observed.

“…This method improved the ductility of Al/Cu hybrid foam and effectively enhanced the energy absorption capacity of opencell foam. Rajak et al [26] studied the compressive behavior of the strain rate between 10 −1 /s and about 10 −3 /s and found that the energy absorption performance of the aluminum foam increased with the stress of the platform. The lower density foam could absorb a large amount of energy.…”

Quasi-static uniaxial compressive tests of open-cell copper (Cu) foams (OCCF) were carried out on an in-situ bi-direction tension/compress testing machine (IBTC 2000). The effects of strain rate, porosity and pore size on the energy absorption of open-cell copper foams were investigated to reveal the energy absorption mechanism. The results show that three performance parameters of open-cell copper foams (OCCF), involving compressive strength, Young modulus and yield stress, increase simultaneously with an increase of strain rate and reduce with increasing porosity and pore size. Furthermore, the energy absorption capacity of OCCF increases with an increase of porosity and pore size. However, energy absorption efficiency increases with increasing porosity and decreasing pore size. The finite element simulation results show that the two-dimensional stochastic model can predict the energy absorption performance of the foam during the compressive process. The large permanent plastic deformation at the weak edge hole is the main factor that affects the energy absorption.
