Computational Methods for Fracture in Porous Media: Isogeometric and Extended Finite Element Methods

Computational Methods for Fracture in Porous Media: Isogeometric and Extended Finite Element Methods provides a self-contained presentation of new modeling techniques for simulating crack propagation in fluid-saturated porous materials. Petroleum engineers will find it to be a unique guide on how to simulate the direction and extent of fracture propagation when pressurizing an existing crack. In addition, environmental engineers will find the simulation tactics for the transport of contaminants in rock faults or fractured salt domes to be very useful, and biomedical engineers will benefit from the applications of these methods to fractures in biologic materials. In the first chapter, the author reviews the basic equations that govern fluid-saturated porous media. In the second chapter, a multi-scale approach to modeling fluid transport in joints, cracks and faults is described in such a way that the resulting formulation allows for a sub-grid representation of the crack and the fluid flow in the crack. In Chapter Three, interface elements are analyzed, with their extension to the hydromechanical case presented. The flexibility of Extended Finite Element Method for non-stationary cracks is also explored and their formulation for fracture in porous media described. The final chapter introduces Isogeometric finite element methods and its basic features and properties. The applications of this book's content cover various fields of Engineering, and, researchers in soil and rock mechanics can use it for simulating pore pressure generation and stress build-up for predicting earthquakes. Teaches both new and upcoming computational techniques for simulating fracture in (partially) fluid-saturated porous mediaHelps readers learn how to couple modern computational methods with non-linear fracture mechanics and flow in porous mediaPresents tactics on how to simulate fracture propagation in hydraulic fracturing INDICE: 1.
