Fracture properties from seismic data – a numerical investigation

Flow Focusing in Unsaturated Fracture Networks: A Numerical Investigation

and become focused. The focused unsaturated flow will increase relative permeability of its path, and cause flow A numerical modeling study is presented to investigate flow– further focusing. Focused flow paths exist in the unsatufocusing phenomena in a large-scale fracture network, constructed rated rock of the Yucca Mountain site. For example, using field data collected from the unsaturated z...

Experimental and Numerical Investigation of Rock Dynamic Fracture

Rapid development of engineering activities expands through a variety of rock engineering processes such as drilling, blasting, mining and mineral processing. These activities require rock dynamic fracture mechanics method to characterize the rock behavior. Dynamic fracture toughness is an important parameter for the analysis of engineering structures under dynamic loading. Several experimental...

Numerical Investigation and Empirical Seismic Vulnerability Assessment of Timber - Framed

Modeling activities and travel for individuals in order to estimate traffic demand leads to large scale simulations. Most current models simulate individuals acting in a mutually independent way except for the use of the shared transportation infrastructure. As soon as cooperation between autonomous individuals is accounted for, the individuals are linked to each other in a network structure an...

Discrimination and Enhancement of Fracture Signals on Surface Seismic Data

Ductile Fracture Modeling - Theory , Experimental Investigation and Numerical Verification

The fracture initiation in ductile materials is governed by the damaging process along the plastic loading path. A new damage plasticity model for ductile fracture is proposed. Experimental results show that fracture initiation in uncracked ductile solids is sensitive to the hydrostatic pressure and is dependent on the Lode angle. The damage plasticity model is established on a "cylindrical dec...
