Abstract
There is a growing demand for high-quality, energy-absorbing structural elements in numerous industry sectors, including automotive, aerospace, building, and biomedical. With growing automobile speeds and possible impact energy, the desire for improved crash-worthiness of the vehicle is a critical concern. This involves the development of innovative materials capable of effectively absorbing and dissipating impact forces, assuring increased safety. Aluminum foam sandwiches (AFSs) with closed cells are among these materials, and because of their lightweight nature, high strength, and excellent energy absorption properties, they can be used as shock absorber structures, such as bumpers, door pillars, and so on, by converting impact energy into plastic deformation energy and keeping the peak force acting on the protected objects below the level that could cause damage.
However, understanding the mechanical behavior of these aluminum foam sandwiches (AFSs) is crucial for a wide range of possible applications
