Megjegyzések:	Taking into consideration the additional weight of a vehicle, today`s requirements can only be met using new materials and designs. The application of metal foam is one of the most promising methods of enhancing the impact energy absorption ability of the crumple zone. The energy-absorbing capacity of thin-walled structures filled with metal foams during compression can be notably improved, which results in lower loading on the passengers. The main goal of our research is to develop a new design that is suited to absorb more impact energy while taking into consideration weight optimization. The authors wanted to unveil the effect of the inhomogeneous filler material in these thin-walled structures. Therefore, the present study investigates the compression test of two metal foams of different densities, in different ways. In the first section, the foams were compressed independently from each other by a recording of a stress-strain diagram. After the single compression, the foams were loaded together, first in parallel, and subsequently in a serial scheme. The study aimed to reveal the effect of the parallel and serial compression scheme focusing on the sum of impact energy absorption.

Cím:	Investigation of the Energy Absorption of the Aluminium Foam / József Kertész, Zoltán Nyikes, Péter Pinke, Tünde Anna Kovács
Dátum:	2022
ISSN:	1742-6588 1742-6596
Megjegyzések:	Abstract. To assure safe traffic is a goal of the vehicle manufacturers. The car body elements are usually made from high plasticity metals whiches can deform in the case of an accident. By this deformation way, the car body absorbs the collision energy. Aluminium foam is a special material that can absorb impact energy. The authors wanted to find a rapid and simple test method to investigate the dynamic load effect for the aluminium foam. The Charpy impact test is a suitable and standardized impact test to determine the absorbed energy of the material during the fracture. In this research, the aluminium foam was tested by the Charpy impact test and compared the results with literature data to evaluate the used impact test.
