The fracture resistance of elastic networks increases with the density of defects like a random walk
Antoine Sanner, Luca Michel, David S. Kammer
Disordered spring networks are a well-established model system to study fracture in a wide range of materials, from ceramics to polymer networks and mechanical metamaterials, acros…

Bridging perturbation and variational approaches in brittle fracture
Serafim Egorov, Antoine Sanner, Jean Sulem +2
We present a variational reduced-order model for three-dimensional coplanar propagation of sharp cracks in heterogeneous perfectly brittle solids under mixed-mode I+II+III loading.…

How Geometry Tames Disorder in Lattice Fracture
Matthaios Chouzouris, Leo de Waal, Antoine Sanner +3
We investigate the fracture behavior of pre-cracked triangular beam-lattices whose elements have failure stresses drawn from a Weibull distribution. Through a statistical analysis…
