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…
Breaking better: How imperfections increase fracture resistance in architected lattices
Alessandra Lingua, Antoine Sanner, François Hild +1
Fracture behavior in architected materials can be influenced by heterogeneities, yet the mechanisms by which imperfections affect crack propagation remain poorly understood. In thi…
Contact point geometry governs structural build-up at rest in Portland cement-limestone blends
Luca Michel, Antoine Sanner, Franco Zunino +2
The early stiffening of fresh cement paste plays a key role in shaping and stability during casting and 3D printing. In Portland cement systems, this phenomenon arises from the for…
Elasticity of bidisperse attractive particle systems
Yaqi Zhao, Antoine Sanner, Luca Michel +1
Bidisperse particle systems are common in both natural and engineered materials, and it is known to influence packing, flow, and stability. However, their direct effect on elastic…
