“…The general behavior of the compression curves was found to be similar to that observed previously [16]. First, samples with the same initial density displayed good reproducibility, which allowed us to verify that a higher stress is needed to deform a more compact sample.…”

“…Indeed, other potential sources of AE could be friction between different fragments or cracking at the corners of the crumpled foil. However, friction was shown to play a negligible role in the deformation of similar samples [16]. Furthermore, the estimate of the upper strain limit at the corners can be obtained by suggesting that the foil is folded over itself.…”

“…On the other hand, randomly crumpled materials, such as polymerized membranes, biological cells, thin paper and metallic sheets, have attracted strong attention in the last decade, because of their fascinating topological features and the scaling laws linking the elastic and plastic properties to the relative density [11][12][13][14][15]. More recently a complete mechanical characterization has been performed on aluminum thin foils [16]. This work highlighted that crumpled materials can present mechanical behavior that is a hybrid between those of foams and entangled fibrous materials.…”

Material properties can be tailored through modification of their geometry or architecture. With this concept, a lot of smart materials, metamaterials, and smart structures have been developed. Auxetic materials and structures are a novel class of materials which exhibit an interesting property of negative Poisson's ratio. By virtue of the auxetic behavior, mechanical properties such as fracture toughness, indentation resistance, etc., can be improved. In order to exploit the interesting properties of auxetic materials, several potential applications of auxetic materials have been explored in medical, sports, automobile, defense, etc. Design and modeling of novel auxetic materials and structures is still on the way. Here, the article focuses upon the different aspects of auxetic materials and structures. A comprehensive updated review of auxetic materials, their types and properties, and applications has been presented. This paper also discusses the design and modeling approaches of auxetic structures.

Finite Element Modeling of Crumpling of Metallic Thin Foil

Crumpled metallic thin foils are very promising as weight‐saving and energy‐absorption materials that can easily be fabricated. To achieve practical industrial applications, it is necessary to improve the understanding of the process of crumpling and the mechanical behavior of crumpled materials considering their complex internal structures. Herein, two possible strategies for computational simulations of crumpled material under closed‐die compression are presented for the first time. The first one entails computations performed at the scale of the foil (direct method), while the second one considers the structure as a continuum with porosity. The analysis performed shows that the continuum‐based approach is more suitable for representing the macroscopic mechanical behavior of crumpled materials with the relative densities ranging from 2% to 40%. An additional benefit is the low computational cost and high efficacy of the porous continuum approach. However, the direct method is shown to be the preferable computational tool when the internal structural patterns changes need to be adequately reproduced, e.g., for a better prediction of the mechanical response under complex loading conditions.
