Elastic softening and fracture in randomly perforated solids
Tero Mäkinen, Alessandro Taloni, Giulio Costantini +3
We study the mechanical response of quasi-brittle polymethyl methacrylate (PMMA) specimens containing controlled random distributions of laser-cut holes. Tensile tests combined wit…
Allometric scaling of brain activity explained by avalanche criticality
Tiago S. A. N. Simões, José S. Andrade, Hans J. Herrmann +2
Allometric scaling laws, such as Kleiber's law for metabolic rate, highlight how efficiency emerges with size across living systems. The brain, with its characteristic sublinear sc…
Fiber bundle model of thermally activated creep failure
Stefan Hiemer, Paolo Moretti, Stefano Zapperi +1
An equal load sharing fiber bundle model for thermally activated breakdown is developed using transition state theory to describe the rate of elementary failures. The lifetime dist…
Fracture toughness and auxeticity in disordered metamaterials
Hannes Holey, Andrea Lorenzo Henri Sergio Detry, Silvia Bonfanti +6
Auxetic metamaterials are commonly thought to exhibit favorable mechanical properties, notably high energy absorption. Here we investigate disordered metamaterials obtained from ra…
From damage percolation to crack nucleation through finite size criticality
Ashivni Shekhawat, Stefano Zapperi, James P. Sethna
We present a unified theory of fracture in disordered brittle media that reconciles apparently conflicting results reported in the literature. Our renormalization group based appro…
