RISConstitutive Behavior and Testing of Structural Adhesives
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Material characterization of structural adhesives in the bulk and bonded forms is discussed. Constitutive relations used for describing stress–strain data are reviewed. The difficulties associated ...
Assessment of Gridded Gravity Anomalies for Precise Geoid Modeling in Turkey
Publisher: ASCE
Abstract: High-accuracy and homogeneously distributed dense terrestrial gravity observations are essential data for detailed analysis of the Earth gravity field as well as for precise modeling of the geoid, which is a natural datum ...
Reduced-Scale Shaking Table Tests on Geosynthetic-Reinforced Soil Walls with Modular Facing
Publisher: American Society of Civil Engineers
Abstract: Reduced-scale shaking table testing is a useful tool for understanding the seismic behavior of geosynthetic-reinforced soil walls. This paper presents the results from a series of reduced-scale shaking table tests on eight ...
Effect of Bentonite Slurry Pressure on Interface Friction of Pipe Jacking
Publisher: American Society of Civil Engineers
Gradation and Packing Characteristics Affecting Stability of Granular Materials: Aggregate Imaging-Based Discrete Element Modeling Approach
Publisher: American Society of Civil Engineers
Abstract: Unbound aggregate base and subbase in layered pavement structures provide an essential function of wheel load distribution through proper angular or crushed particle interlocking of coarse aggregate particles in the granular ...
A Methodology to Determine Work Material Flow Stress and Tool-Chip Interfacial Friction Properties by Using Analysis of Machining
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we develop a methodology to determine flow stress at the machining regimes and friction characteristics at the tool-chip interface from the results of orthogonal cutting tests. ...
Anisotropic Modular Ratios as Unbound Aggregate Performance Indicators
Publisher: American Society of Civil Engineers
Abstract: Standard repeated load triaxial tests commonly performed in the laboratory do not always apply the most damaging field loading conditions for predicting resilient and permanent deformation (rutting) responses of unbound ...
Aggregate Physical Properties Affecting Modulus and Deformation Characteristics of Unsurfaced Pavements
Publisher: American Society of Civil Engineers
Abstract: This paper presents findings from a recently completed research study at the University of Illinois aimed at investigating the effects of aggregate type and quality on mechanistic pavement response and rutting performance ...
Aggregate Morphology Affecting Strength and Permanent Deformation Behavior of Unbound Aggregate Materials
Publisher: American Society of Civil Engineers
Abstract: This paper presents findings of a research study focused on investigating influences of coarse aggregate morphologies on the strength and permanent deformation behavior of unbound aggregate materials. Angularity and surface ...
Image-Aided Element Shape Generation Method in Discrete-Element Modeling for Railroad Ballast
Publisher: American Society of Civil Engineers
Abstract: The discrete-element method (DEM) provides more realistic results compared with those of continuum analysis for unbound construction materials such as railroad ballast. This paper introduces a digital-image aided particle-shape ...
