RISThermo-Hydro-Mechanical Model for Unsaturated Clay Soils Based on Granular Solid Hydrodynamics Theory
Publisher: American Society of Civil Engineers
Abstract: Starting from the thermodynamic framework of a mixture, combined with the modified soil-water characteristic curve (SWCC) model, and considering the granular-level energy dissipation caused by temperature and saturation ...
Stability Analysis of Prescribed Slip Surfaces Based on a Combination of the Equilibrium Equation and the Critical Unstable Condition
Publisher: American Society of Civil Engineers
Abstract: Stability analysis of potential slip surfaces is one of the core steps of slope safety evaluation. In this study, a novel model was developed that considers the critical unstable condition that represents the limit equilibrium ...
Implementation of the Critical Unstable Condition in Extended Finite-Element Analysis to Calculate the Safety Factor of a Predefined Slip Surface
Publisher: American Society of Civil Engineers
Abstract: This study incorporated the critical unstable condition into extended finite-element analysis to determine the safety factor of a slip surface that is regarded as a discontinuity embedded into the slope mesh. The displacement ...
Characterization of Scandia Stabilized Zirconia Doped With Various Bi2O3 Additions as an Intermediate Temperature Solid Oxide Fuel Cell Electrolyte
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bi2O3 doped scandia stabilized zirconia systems have shown promise for use as electrolytes in intermediate temperature solid oxide fuel cells (IT-SOFC's). Sintering properties, crystal phase ...
Evaluation Approach of the Slope Stability Based on Deformation Analysis
Publisher: American Society of Civil Engineers
Abstract: Once a slope is led to the limit equilibrium state using the strength-reduction method, the displacement contours located near the critical slip surface are quite close. The critical slip surface is composed of the points ...
Application of a Thermodynamic Framework–Based Constitutive Model for Hydrate-Bearing Sediment Considering Grain Breakage and Stress History
Publisher: American Society of Civil Engineers
Abstract: The physical cementation and grain breakage effects play a vital role in influencing the mechanical properties of hydrate-bearing sediment. In this study, a thermodynamic model for hydrate-bearing sediment considering ...
