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…

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…
