RISAssessing the Reliability of Rock Slopes Based on the Nonlinear Strength Criterion
Publisher: American Society of Civil Engineers
Abstract: Traditionally, the reliability of a rock slope is evaluated based on the linear Mohr–Coulomb strength criterion, neglecting the nonlinear shear strength of the majority of geotechnical materials. The paper proposes a ...
Dynamic Stress Concentration of a Circular Cutout Buried in Semi-Infinite Plates Subjected to Flexural Waves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, based on the theory of elastic thin plates, applying the image method and the wave function expansion method, multiple scattering of elastic waves and dynamic stress concentration ...
Resilience-Driven System Design of Complex Engineered Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Most engineered systems are designed with a passive and fixed design capacity and, therefore, may become unreliable in the presence of adverse events. Currently, most engineered systems are ...
A Generalized Complementary Intersection Method (GCIM) for System Reliability Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a Generalized Complementary Intersection Method (GCIM) that can predict system reliability for series, parallel, and mixed systems. The GCIM is an extension of the original ...
Random Field Characterization Considering Statistical Dependence for Probability Analysis and Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The proper orthogonal decomposition method has been employed to extract the important field signatures of random field observed in an engineering product or process. Our preliminary study found ...
Effect of Acid Rain on Mechanical Properties and Aging Mechanism of Asphalt
Publisher: American Society of Civil Engineers
Abstract: Through the preparation of nitric acid–type acid rain, mixed acid rain, and sulfuric acid–type acid rain, an experimental method of periodic soaking of asphalt was developed. Then, using a four-component test, the ...
Influence of Molding Process on the Performance of Sisal Fiber Cement–Emulsified Asphalt Mixture
Publisher: American Society of Civil Engineers
Abstract: In order to explore the influence of the molding process on the performance of sisal fiber cement–emulsified asphalt mixture, specimens were formed by different molding processes. Different mixing methods, mixing times, ...
Relationship between Microstructure and Macroscopic Properties of Asphalt under Different Concentrations of Snow Melting Agent
Publisher: ASCE
Abstract: This paper explored the relationship between microstructure characteristics and macroscopic properties of asphalt under different concentrations of snowmelt agent. Using penetration tests, ductility tests, softening point ...
Underwater Explosion Resistance Performance of an Old Gravity Dam without Good Longitudinal-Joint Connection Integrity: Coupled Acoustic-Structural Analysis
Publisher: ASCE
Abstract: A gravity dam monolith bounded by the transverse contraction joints on both sides is usually recognized as an independent element in various dynamic analyses. However, in most cases a gravity dam monolith is actually ...
Dynamic Stress of a Circular Cavity Buried in a Semi-Infinite Functionally Graded Material Subjected to Shear Waves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The multiple scattering of shear waves and dynamic stress in a semi-infinite functionally graded material with a circular cavity is investigated, and the analytical solution of this problem is ...
