Extended finite element framework for fault rupture dynamics including bulk plasticity
extended finite elements fault rupture dynamics bulk plasticity
2015/7/1
We present an explicit extended finite element framework for fault rupture dynamics accommodating bulk plasticity near the fault. The technique is more robust than the standard split-node method becau...
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...

Granular materials Strain localization
2015/7/1
Development of more accurate mathematical models of discrete granular material behavior requires a fundamental understanding of deformation and strain localization phenomena. This paper utilizes a mes...
A finite element model of localized deformation in frictional materials taking a strong discontinuity approach
finite element model localized deformation frictional materials strong discontinuity approach
