RISThe Stress Analysis and Experimental Research of Tubular K-Joints With Overlap
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The geometry of overlapping tubular joints, the equations of intersection curves and the coordinate of the intersection point are introduced first. The variational method for simple tubular joints ...
Optimal Curve Fitting for Serial Chain in Six-Crease Origami Unit
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Origami-inspired structures have been widely used in aerospace and robotics for three-dimensional (3D) symmetrical configurations using crease-symmetrical origami basic patterns. These patterns offer advantages in repeatable ...
Design of PAM and PWM Controllers for Sampled-Data Interval Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we address two issues: digital redesign of a continuous-time interval system using an interval chebyshev quadrature approximation method; and translation of the newly digitally ...
Hydraulic Fracturing and Self-Healing Behavior in Compacted Bentonite: Insights from Visualization Experiments
Publisher: American Society of Civil Engineers
Abstract: Understanding the hydraulic fracturing and self-healing behavior of compacted bentonite is essential for the long-term performance evaluation of engineered barriers in deep geological disposal. In this study, cyclic hydraulic ...
Interface Dynamic Shear Characteristics of Aging GMB/CCL Composite Liner
Publisher: American Society of Civil Engineers
Abstract: Aging degradation of the geomembrane (GMB) significantly influences the dynamic shear characteristics of the composite liner interface, which comprises the GMB and the compacted clay liner (CCL), potentially jeopardizing ...
Investigations of Flutter and Aerodynamic Damping of a Turbine Blade: Experimental Characterization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flutter is a self-excited and self-sustained aero-elastic instability, caused by the positive feedback between structural vibration and aerodynamic forces. A two-passage linear turbine cascade was designed, built, and ...
Experimental Investigation of Nonlinear Flow Characteristics of Real Rock Joints under Different Contact Conditions
Publisher: American Society of Civil Engineers
Abstract: Laboratory experiments were conducted on three artificial rock joints with natural characteristics to study the nonlinear fluid flow characteristics in a single joint under different contact conditions. A noncontact, ...
Interdecadal Connection between Arctic Temperature and Summer Precipitation over the Yangtze River Valley in the CMIP5 Historical Simulations
Publisher: American Meteorological Society
Abstract: his study assesses the ability of the Coupled Model Intercomparison Project phase 5 (CMIP5) simulations in capturing the interdecadal precipitation enhancement over the Yangtze River valley (YRV) and investigates the ...
Water-Stage Forecasting in a Multitributary Tidal River Using a Bidirectional Muskingum Method
Publisher: American Society of Civil Engineers
Abstract: The Muskingum flow routing method has been successfully used in many hydrologic applications due to its simplicity in concept and calculation. This paper presents a bidirectional Muskingum water-stage routing model (BDMWSRM) ...
Insights into Determination of Gas Breakthrough in Saturated Compacted Gaomiaozi Bentonite
Publisher: ASCE
Abstract: Gas breakthrough pressure is of great importance for evaluating the sealing efficiency and assessing the long-term performance of saturated buffering materials with low permeability in the deep geological disposal of ...
