Study on Impact Performance of Metamaterial Energy Absorbing Devices WitrynaFoam is substance obtained as a result of trapping gas in liquid or solid. The gas pockets make foam very light weight and at the time of impact most of the energy is absorbed by the material and hence it helps in minimising the damage of impact. Metal Foam Impact Dampers. Metal foam was first seen in 1926 by Meller in a French patent.
Witryna1 maj 2011 · Lavoie and Morton [] designed a dedicated crush test fixture (the NASA fixture) for measuring energy absorption of rectangular composite plates.The flat-plate specimen is stabilized by knife edges which aim to simulate the end conditions of closed structures. The crushing results indicate that the load-displacement curves of flat … Witryna7 mar 2024 · Microwave heating is widely employed in pavement deicing. However, it is difficult to improve the deicing efficiency because only a small part of the microwave energy is used and most of it is wasted. To improve the utilization efficiency of microwave energy and the deicing efficiency, we used silicon carbide …
Witryna9 wrz 2024 · The highest impact energy dispersion was observed for the honeycomb structure made of EVA material. Both proposed structures show good mechanical properties allowing the absorption of the impact energy, however, in the case of the honeycomb geometry, the stiffness is higher and this is insufficient to protect the skull … Witryna21 mar 2024 · In this work, the mechanical behavior and energy absorption characteristics of flexible fabric under hypervelocity impact (HVI) were investigated. Basalt fabric, ultra-high molecular weight polyethylene (UHMWPE) fabric, and aluminum alloy (Al) plate were chosen to be the sample materials for their excellent mechanical …
Witryna31 sie 2024 · High strain rates or impact loads are almost unavoidable in composite material applications; thus, their static strength is not the only consideration, and impact behavior and energy absorption properties are also crucial . In some instances, efforts to refine the in-plane mechanical properties lead to compromise in impact performance.
