“…The CAFMs start to behave as a continuum under further loading. Similar observations are reported by the [19,21]. This is unlike the behavior of metal foams that show a long plateau after the yield stress before eventually reaching the densification strain [4].…”

“…Limited work has been carried out on crumpled sheet materials. Only three main studies reported in [19,20,21] have been carried out which investigate crumpled aluminium foil as a comparative material to other cellular materials. Bouaziz et al [19] compared their results of crumpled aluminium foil to commercial metal foams and found they may have similar potential as a low cost alternative in some instances due to some shared characteristics.…”

Effect of Relative Density on Compressive Load Response of Crumpled Aluminium Foil Mesh

In recent years, a large number of metal foams and porous metals have been developed. Due to the high cost of these materials alternative manufacturing methods for cellular metallic materials are being explored. Crumpled metallic foil meshes, manufactured via die compression techniques, are evolving as a potential alternative method. However, the non-availability of sufficient data on their load response is limiting their uptake. Uniaxial compressive load response of crumpled aluminium foil meshes (CAFMs) of varying densities, forged by open and closed die compression, are studied. A 0.05 mm thick aluminium sheet mesh, manufactured by the expanded metal process is used. X-ray computed micro-tomography is employed to image the CAFM’s internal cellular structure. The stress-strain relation demonstrates that the CAFMs produce identical load response profile irrespective of their relative density. Power law functions ER=17110ρr3.6547 and σY,E=53.092ρr2.2249 define the relationships between real Young’s Modulus ER and effective yield strength, σY,E. The study provides new knowledge on the effect of relative density on the compressive properties of CAFMs which have applications across lightweight structural design.

“…The propensity to buckle is best understood by examining shell geometry, which contrasts one exceptionally thin length scalethe thickness-against a much larger length scale (shell diameter, radius of curvature, or "characteristic length") [Balankin et al 2015;Sethna et al 2001;Wood 2002;Vliegenthart and Gompper 2006]. A remarkable consequence of the contrasting length scales is that the membrane stiffness is several orders of magnitude greater than the bending stiffness, leading to a preference of bending (normal deflection) over membrane (in plane compression) modes.…”

“…For certain geometries, a rapid cascade of buckling events leads to crumpling [Cerda et al 1999]. At first glance appearing to be absolutely unorganized, the geometry of crumpling is in fact statistically reproducible [Balankin et al 2015].…”

Crumpled-based materials are relatively easy to fabricate and show robust mechanical properties for practical applications, including meta-biomaterials design aimed for improved tissue regeneration. For such requests, however, the structure needs to be porous. We introduce a crumpled holey thin sheet as a robust bio-metamaterial and measure the mechanical response of a crumpled holey thin Mylar sheet as a function of the hole size and hole area fraction. We also study the formation of patterns of crease lines and ridges. The area fraction largely dominated the crumpling mechanism. We also show, the crumpling exponents slightly increases with increasing the hole area fraction and the total perimeter of the holes. Finally, hole edges were found to limit and guide the propagation of crease lines and ridges.
