RISImpermeable Crack and Permeable Crack Assumptions, Which One is More Realistic?
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the applicability and effect of the crack-free electrical boundary conditions in piezoelectric fracture. By treating flaws in a medium as notches with a finite width, the ...
Closed-Form Solution for an Antiplane Interface Crack between Two Dissimilar Magnetoelectroelastic Layers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In recent years, ferroelectromagnetic laminated composites have aroused worldwide research interest. In this paper, we developed a closed-form solution for antiplane mechanical and in-plane electric ...
Thermal Shock Strength of a Semi-infinite Piezoelectric Medium
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper considers the mechanical problem of a semi-infinite piezoelectric medium under sudden thermal load. The medium contains an electrically conducting crack perpendicular to its surface. ...
Full-Scale Specimen Testing and Parametric Studies on Tensile-Plate Cable-Girder Anchorages in Cable-Stayed Bridges with Steel Girders
Publisher: American Society of Civil Engineers
Abstract: In cable-stayed bridges, cable anchorages are subject to significant forces in the structure and carry a heavy stress concentration. The structural features and cable-force transfer pathway of four typical cable-girder ...
Estimating Static and Dynamic Stresses in Geosynthetic-Reinforced Pile-Supported Track-Bed under Train Moving Loads
Publisher: American Society of Civil Engineers
Abstract: This study presents an estimating method to calculate the static and the dynamic stresses in the geosynthetic-reinforced pile-supported track-bed (embankment), based on a series of full-scale model tests under train moving ...
Modulation by the QBO of the Relationship between the NAO and Northeast China Temperature in Late Winter
Publisher: American Meteorological Society
Abstract: The North Atlantic Oscillation (NAO) generally has an in-phase relationship with surface air temperature (SAT) anomalies over Northeast China in late winter. The present study shows that such an NAO–SAT relationship becomes ...
Investigation on the Microstructure, Unconfined Compressive Strength, and Thermal Conductivity of Compacted CDG Soil by MICP Treatment during Curing
Publisher: American Society of Civil Engineers
Abstract: As an eco-friendly treatment method, the microbially induced calcite precipitation (MICP) approach has been widely adopted in sand, but its use on compacted fine-grained soils remains scarce. In this study, compacted ...
Evolution of Tunnel Uplift Induced by Overlying Oblique Intersection Angle Excavation and an Effective Protection Measure
Publisher: American Society of Civil Engineers
Abstract: The release of ground stress brought on by overlying excavation poses a significant threat to regular tunnel operation, especially when the foundation pit intersects the tunnel inclination, and the torsional deformation ...
Weld-Quality Diagnosis of In-Service Natural Gas Pipelines Based on a Fusion Model
Publisher: American Society of Civil Engineers
Abstract: Damage to pipeline welds during service can result in substantial human and economic losses. Hence, early and accurate quality diagnosis of in-service natural gas pipeline welds is of utmost importance. However, the current ...
