Modeling the dynamic rupture propagation on heterogeneous faults with rate- and state-dependent friction
dynamic rupture fault constitutive law fault friction stress heterogeneities
2015/9/10
We investigate the effects of non-uniform distribution of constitutive parameters on the dynamic propagation of
an earthquake rupture. We use a 2D finite difference numerical method and we assume tha...
Embedded strong discontinuity finite elements for fractured geomaterials with variable friction
bifurcation rate- and state-friction strong discontinuity enhanced strain finite element
2015/7/1
The strong discontinuity approach to modelling strain localization, combined with an enhanced strain element, has been used for more than a decade to model strain localization in materials including g...
An extended finite element framework for slow-rate frictional faulting with bulk plasticity and variable friction
extended finite element friction fault plasticity
2015/7/1
We present an extended finite element (FE) approach for the simulation of slow-rate frictional faulting in geologic media incorporating bulk plasticity and variable friction. The method allows the fau...

2015/7/28
Key methods developed and used in the USSR and in the Russian Federation to determine the impact and friction sensitivity of energetic materials and explosives have been discussed. Experimental metho...
MICROTOPOGRAPHY – THE PHOTOGRAMMETRIC DETERMINATION OF FRICTION SURFACES
Microphotogrammetry Microtopography Close Range Matching Digital Surface Model Change Detection
2015/1/6
The understanding of friction processes assumes numerous methods for analysing the features and changes of surfaces in micro- and nanoscale. One of these features is the three-dimensional characterisa...
The present paper - a continuation of our recent series of papers on Casimir friction for a pair of particles at low relative particle velocity - extends the analysis so as to include dense media. The...
Low friction along the high slip patch of the 2011 Mw 9.0 Tohoku-Oki earthquake required from the wedge structure and extensional splay faults
Low friction along the high slip patch 2011 Mw 9.0 Tohoku-Oki earthquake required the wedge structure extensional splay faults
2014/4/15
We analyze the mechanical properties needed to account for the large shallow slip during the 2011 Tohoku-Oki earthquake and the activation of landward normal faulting within the forearc. We show that ...

The American Revolution (1775-1783) resulted in the independence of 13 of Great
Britain’s North American colonies. In the 1780s, leaders of the new American nation
realized that the national gover...
Megathrust friction determined from mechanical analysis of the forearc in the Maule earthquake area
Maule earthquake frictional properties dynamic weakening critical wedge
2014/4/15
The seismogenic potential of a given fault depends essentially on its frictional properties and on the mechanical properties of the medium. Determining the spatio-temporal variations of frictional pro...
Non-stationary patterns of isolation-by-distance: inferring measures of genetic friction
landscape genetics gene flow genetic barrier isolation by distance,non-stationary kriging
2012/11/26
The pattern of isolation-by-distance arises when population differentiation increases with increasing geographic distances. This pattern is usually caused by local spatial dispersal which explains why...
