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…
Structural build-up at rest in the induction and acceleration periods of OPC
Luca Michel, Lex Reiter, Antoine Sanner +2
Structural build-up in fresh cement paste at rest is characterized by time evolutions of storage modulus and yield stress, which both increase linearly in time during the induction…
Eulerian framework for contact between solids represented as phase fields
Flavio Lorez, Mohit Pundir, David S. Kammer
Mechanical contact between solids is almost exclusively modeled in Lagrangian frameworks. While these frameworks have been developed extensively and applied successfully to numerou…
Transonic and supershear crack propagation driven by geometric nonlinearities
Mohit Pundir, Mokhtar Adda-Bedia, David S. Kammer
Linear elastic fracture mechanics theory predicts that the speed of crack growth is limited by the Rayleigh wave speed. Although many experimental observations and numerical simula…
The deflection limit of slab-like topologically interlocked structures
Silvan Ullmann, David S. Kammer, Shai Feldfogel
Topologically Interlocked Structures (TIS) are structural assemblies that achieve stability and carrying capacity through the geometric arrangement of interlocking blocks, relying…
An FFT-based framework for predicting corrosion-driven damage in fractal porous media
Mohit Pundir, David S. Kammer, Ueli Angst
Understanding fracture in cementitious materials caused by the deposition and growth of corrosion products requires scale-bridging approaches due to the large length-scale differen…
Scaling, saturation, and upper bounds in the failure of topologically interlocked structures
Shai Feldfogel, Konstantinos Karapiperis, Jose Andrade +1
Topological Interlocking Structures (TIS) have been increasingly studied in the past two decades. However, some fundamental questions concerning the effects of Young's modulus and…
Failure of topologically interlocked structures -- a Level-Set-DEM approach
Shai Feldfogel, Konstantinos Karapiperis, Jose Andrade +1
Topological Interlocking Structures (TIS) are assemblies of interlocking building blocks that hold together solely through contact and friction at the blocks' interfaces, and thus…
Nucleation of frictional slip: A yielding or a fracture process?
Miguel Castellano, Flavio Lorez, David Kammer
The onset of frictional sliding between contacting bodies under shear load is nucleated by the quasi-static growth of localized slip patches. After reaching a certain critical size…
Nucleation of frictional sliding by coalescence of microslip
Styfen Schär, Gabriele Albertini, David S. Kammer
The onset of frictional motion is mediated by the dynamic propagation of a rupture front, analogous to a shear crack. The rupture front nucleates quasi-statically in a localized re…
Stochastic Properties of Static Friction
Gabriele Albertini, Simon Karrer, Mircea D. Grigoriu +1
The onset of frictional motion is mediated by rupture-like slip fronts, which nucleate locally and propagate eventually along the entire interface causing global sliding. The stati…
Effective toughness of heterogeneous materials with rate-dependent fracture energy
Gabriele Albertini, Mathias Lebihain, François Hild +2
We investigate dynamic fracture of heterogeneous materials experimentally by measuring displacement fields as a rupture propagates through a periodic array of obstacles of controll…
