Solitonic State in Microscopic Dynamic Failures
H. O. Ghaffari, M. Pec, W. A. Griffith
Onset of permanent deformation in crystalline materials under a sharp indenter tip is accompanied by nucleation and propagation of defects. By measuring the spatio-temporal strain…
Dynamic Evolution of Microscopic Wet Cracking Noises
H. O. Ghaffari, W. A. Griffith, P. M. Benson
Characterizing the interaction between water and microscopic defects is one of the long-standing challenges in understanding a broad range of cracking processes. Different physical…
Faulting of rocks at three-dimensional stress field by micro-anticracks
H. O. Ghaffari, M. H. B. Nasseri, R. Paul Young
Using 9-sets of different laboratory earthquake tests, we examined the nature of cracking under true triaxial stress conditions in the lithosphere . We found that 3D stress state c…
Functional-Friction Networks: New Insights on the Laboratory Earthquakes
H. O. Ghaffari, B. D. Thompson, R. P. Young
We report some new applications of functional complex networks on acoustic emission waveforms from frictional interfaces. Our results show that laboratory faults undergo a sequence…
Acoustic-Friction Networks and the Evolution of Precursory Rupture Fronts in Laboratory Earthquakes
H. O. Ghaffari, R. P. Young
We show that the mesoscopic and transport characteristics of networks follow the same trends for the same type of the shear ruptures in terms of rupture speed while also comparing…
Network Theory, Cracking and Frictional Sliding
H. O. Ghaffari, R. P. Young
We have developed different network approaches to complex patterns of frictional interfaces (contact areas developments). Here, we analyze the dynamics of static friction. We found…
