Opening-mode fractures in layered materials, such as sedimentary rocks, pavement, functionally graded composite materials or surface coating films, often are periodically distributed with spacings scaled to the thickness of the fractured layer. The current general explanation is that when the fracture spacing to layer thickness ratio changes from greater than to less than critical values the no...

In petroleum production, Produced Water Re-Injection (PWRI) has earned much interest among disposal methods of the produced water. However, presence of the contaminants in the produced waters usually results in formation damage in well bores and their surrounding fracture systems. In the present study, modeling of external cake formation on a fracture in unsteady-state conditions i...

In concrete pavements, a single concrete mixture design is selected to resist mechanical loading without attempting to adversely affect the concrete pavement shrinkage, ride quality, or noise attenuation. An alternative approach is to design distinct layers within the concrete pavement surface which have specific functions thus achieving higher performance at a lower cost. The objective of this...

This paper presents a modeling approach for studying hydro-mechanical coupled processes, including fracture development, within geological formations. This is accomplished through the novel linking of two codes: TOUGH2, which is a widely used simulator of subsurface multiphase flow based on the finite volume method; and an implementation of the Rigid-BodySpring Network (RBSN) method, which prov...

Fractured reservoirs contain about 85 and 90 percent of oil and gas resources respectively in Iran. A comprehensive study and investigation of fractures as the main factor affecting fluid flow or perhaps barrier seems necessary for reservoir development studies. High degrees of heterogeneity and sparseness of data have incapacitated conventional deterministic methods in fracture network modelin...

This master thesis focuses on the study of the state of the art on crack and fracture modeling. This process is one of the aging phenomena with an important amount of work done, due to its complexity and its extended application area. The variety of parameters and the complex simulation (usually implying collision detection, deformations, breakage, etc), make difficult to think on a generic sol...
