Abstract: Carbon micro/nanolattice materials, defined as three-dimensional (3D) architected metamaterials made of micro/nanoscale carbon constituents, have demonstrated exceptional mechanical properties, including ultrahigh specific ...

Abstract: Nanotwinned metals are a class of hierarchically structured materials that appear to transcend the limits of conventional material systems by exhibiting an exceptional combination of superior strength, ductility and ...

Abstract: The low fracture toughness of graphene has raised sharp questions about its strength in the presence of cracklike flaws. Here, we discuss a number of recent studies that suggest some promising routes as well as open questions ...

Abstract: Loadbearing biological materials such as bone, teeth, and nacre have acquired some interesting mechanical properties through evolution, one of which is the tolerance of cracklike flaws incurred during tissue function, ...

Abstract: Democratized mechanical testing offers a promising solution for enabling the widespread adoption of recycled and renewably sourced feedstocks. Locally sourced, sustainable materials often exhibit variable mechanical ...

Abstract: Temperatureand stiffnessdependent edge forces offer new mechanisms of designing nanodevices driven by temperature and stiffness gradients. Here, we investigate the edge forces in a graphene nanolayer on a spring supported ...

Abstract: An efficient numerical method is developed to analyze the mechanical responses of tensegrity structures subjected to various actuations that lead to large and highly nonlinear (e.g., hardening or softening) deformations. ...

Abstract: A theoretical model is developed to investigate the mechanical behavior of closely packed carbon nanoscrolls (CNSs), the socalled CNS crystals, subjected to uniaxial lateral compression/decompression. Molecular dynamics ...

Abstract: Molecular dynamics simulations are performed to investigate the effect of surface energy on equilibrium configurations and selfcollapse of carbon nanotube bundles. It is shown that large and reversible volumetric deformation ...

Abstract: Aside from ultrahigh strength and elasticity, metallic glasses (MGs) possess a number of favorable properties. However, their lack of dislocation based plastic deformation mechanisms in crystalline metals and the resulting ...
