RISFace Stability Evaluation of a TBM-Driven Tunnel in Heterogeneous Soil Using a Probabilistic Approach
Publisher: American Society of Civil Engineers
Abstract: The stability condition of the tunnel face is of great importance in both conventional and modern [tunnel-boring machine (TBM)] methods of construction. Inadequate and excessive amounts of support pressure toward the face ...
Eulerian Framework for Inelasticity Based on the Jaumann Rate and a Hyperelastic Constitutive Relation—Part I: Rate Form Hyperelasticity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An integrable Eulerian rate formulation of finite deformation elasticity is developed, which relates the Jaumann or other objective corotational rate of the Kirchhoff stress with material spin to the same rate of the left ...
Eulerian Framework for Inelasticity Based on the Jaumann Rate and a Hyperelastic Constitutive Relation—Part II: Finite Strain Elastoplasticity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An Eulerian rate formulation of finite strain elastoplasticity is developed based on a fully integrable rate form of hyperelasticity proposed in Part I of this work. A flow rule is proposed in the Eulerian framework, based ...
Numerical Simulation of the Impact of Natural Fracture on Fluid Composition Variation Through a Porous Medium
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to lessen the computational time in fractured oil reservoir simulations, all fractures are usually assumed to be as one equivalent fracture at the center or around the model. This, specially, has applications in ...
State-of-the-Art Solution of Capacitance Resistance Model by Considering Dynamic Time Constants as a Realistic Assumption
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To have an acceptable accuracy for water flooding projects, proper history matching is an important tool. Capacitance resistance model (CRM) simulates water flooding performance based on two tuning parameters of time ...
