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...
Finite element simulation of strain localization with large deformation: capturing strong discontinuity using a Petrov–Galerkin multiscale formulation
Finite element simulation strain localization with large deformation strong discontinuity Petrov–Galerkin multiscale formulation
2015/7/1
The finite element model for strain localization analysis developed in a previous work is generalized to the finite deformation regime. Strain enhancements via jumps in the displacement field are capt...

finite element model localized deformation frictional materials strong discontinuity approach
2015/7/1
A finite element model of localized deformation in frictional materials taking a strong discontinuity approach is presented. A rate-independent, non-associated, strain-softening Drucker-Prager plastic...
DISCONTINUITY SURFACE ROUGHNESS MEASUREMENT TECHNIQUES AND THE EVALUATION OF DIGITAL PHOTOGRAMMETRIC METHOD
Joint surface roughness Roughness measurement techniques
2015/6/1
The development of the knowledge from classical photogrammetry to digital photogrammetry is provided simplicity on the works
carried out either on the field or on the laboratory. As a result of this...
SURFACE DISCONTINUITY MODELLING BY LSM THROUGH PATCH ADAPTATION AND USE OF EDGES
edges least squares matching modelling
2015/6/1
This paper handles the aspect of least squares matching (LSM) for DSM generation and focuses mainly on the exploitation of edge
information in the least squares approach. The mathematical model of L...
