Stochastic dynamics of a sheared granular medium
Alberto Petri, Andrea Baldassarri, Fergal Dalton +3
We experimentally investigate the response of a sheared granular medium in a Couette geometry. The apparatus exhibits the expected stick-slip motion and we probe it in the very int…
Anomalous Roughness of Fracture Surfaces in 2D Fuse Models
Phani K. V. V. Nukala, Stefano Zapperi, Mikko Alava +1
We study anomalous scaling and multiscaling of two-dimensional crack profiles in the random fuse model using both periodic and open boundary conditions. Our large scale and extensi…
Fracture size effects from disordered lattice models
Mikko J. Alava, Phani K. V. V. Nukala, Stefano Zapperi
We study size effects in the fracture strength of notched disordered samples using numerical simulations of lattice models for fracture. In particular, we consider the random fuse…
Discrete Fracture Model with Anisotropic Load Sharing
R. C. Hidalgo, S. Zapperi, H. J. Herrmann
A two-dimensional fracture model where the interaction among elements is modeled by an anisotropic stress-transfer function is presented. The influence of anisotropy on the macrosc…
Grain Boundary Diffusion in a Peierls-Nabarro Potential
F. Leoni, S. Zapperi
We investigate the diffusion of a grain boundary in a crystalline material. We consider in particular the case of a regularly spaced low-angle grain boundary schematized as an arra…
