RISTest and Study on the Long-Age Performance of Cement Concrete Pavement Material
Publisher: American Society of Civil Engineers
Abstract: Experimental research is conducted to determine the long—age statistical parameters of road pavement properties such as flexural strength, flexural elastic modulus, compressive strength, and splitting strength after ...
Use of Continuous-Wavelet Transmissibility for Structural Operational Modal Analysis
Publisher: American Society of Civil Engineers
Abstract: Operational modal analysis is a challenging task to deal with output-only vibration measurements contaminated by noise. This paper proposes a new method for operational modal identification of a linear system using ...
Generalized Proper Complex Gaussian Ratio Distribution and Its Application to Statistical Inference for Frequency Response Functions
Publisher: American Society of Civil Engineers
Abstract: The frequency response function governs many important processes. Defined as the quotients of the fast Fourier transform coefficients, frequency response functions can be modeled as ratio random variables in the complex ...
Energy Conversion Efficiency of Thermoelectric Power Generators With Cylindrical Legs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermoelectric power generators (TEGs) have been attracted increasing attention due to their capability of converting waste heat into useful electric energy without hazardous emissions. Many theoretical models to conduct ...
Study on the Salt Scaling Resistance of Pavement Cement Concrete
Publisher: American Society of Civil Engineers
Abstract: The single-side salt-freeze test was used to optimize the concrete mix design for improving the resistance of concrete to salt scaling. The results show that the resistance of concrete to salt scaling improves with decreasing ...

Axial Vibration Suppression in a Partial Differential Equation Model of Ascending Mining Cable Elevator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Lifting up a cage with miners via a mining cable causes axial vibrations of the cable. These vibration dynamics can be described by a coupled wave partial differential equation-ordinary differential equation (PDE-ODE) ...
The Approximate Analysis of Higher-Order Frequencies of Nonlinear Vibrations of a Cantilever Beam With the Extended Galerkin Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonlinear vibrations of elastic beams with large amplitudes are frequently treated as a typical problem of an elastica. As the continuation of the analysis of the deformation of an elastica, the nonlinear vibration ...
Accuracy of Individual Trabecula Segmentation Based Plate and Rod Finite Element Models in Idealized Trabecular Bone Microstructure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Currently, specimenspecific micro finite element (خ¼FE) analysis based micro computed tomography (خ¼CT) images have become a major computational tool for the assessment of the mechanical properties of human trabecular bone. ...
Creep-Fatigue Behaviors and Life Assessments in Two Nickel-Based Superalloys
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The aim of this paper is to investigate different factors, including dwell time, strain range, and strain ratio on creep-fatigue endurances in nickel-based Inconel 718 and GH4169 superalloys. We also summarize classic ...
