Additional information

This paper shows through MD simulations and theoretical analysis how overall strength and damage reduction in spider webs after insect impacts is optimized by hyperelastic constitutive behaviour, as opposed to linear-elastic or elasto-plastic laws. This concept has become a defining paradigm for Pugno’s ERC Starting grant (2011) on ‘Bioinspired hierarchical super nanomaterials’, with applications to flaw tolerant design. The paper featured on the cover of Nature and had significant worldwide impact (e.g. press releases and a feature article in Nature Materials). It led to invited talks at various events incl. ‘Falling Walls’ and the ‘World Economic Forum’.
