RISHydromechanical Behaviors of Unsaturated Soils
Publisher: American Society of Civil Engineers
Abstract: In this paper, the hydromechanical behavior of unsaturated soils is explored. A constitutive model is proposed to describe the coupled hydraulic and mechanical behavior of unsaturated soils. The compression stiffness ...
Why Modeling Particle Shape Matters: Significance of Particle-Scale Modeling in Describing Global and Local Granular Responses
Publisher: American Society of Civil Engineers
Abstract: The applicability of particle-scale modeling using the discrete-element method (DEM) is typically evaluated by comparing simulation results with stress–strain responses observed in elementary tests. This validation at the ...
Establishment of Nonlinear Dynamic Model for Prediction of Rotordynamic Instability of Steam Turbine Rotor-Bearing System Caused by Partial Admission
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A nonlinear dynamic model is developed for a rotor-bearing system with radial steam force due to partial admission, taking into account the prediction of subsynchronous instability of a steam ...
Research on Productivity Prediction Model of Three-Dimensional Directional Wells in Different Reservoirs
Publisher: ASCE
Abstract: Productivity prediction of perforation completion is key for well optimizing completion methods and reservoir engineering research. Productivity prediction models using an additional pressure drop to represent skin factor ...
