RISPropagation Characteristics of Dispersion Cracks in Asphalt Concrete at Low Temperatures
Publisher: American Society of Civil Engineers
Abstract: Asphalt concrete is a typical heterogeneous composite material at the mesoscale. Under the action of external load, its internal dispersion cracks interact with each other, thereby changing the crack propagation behavior, ...
Local Thermal Nonequilibrium During Melting of a Paraffin Filled in an Open-Cell Copper Foam: A Visualized Study at the Pore-Scale
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this technical brief, the application of infrared thermal imaging to investigate melting of a phase-change material (PCM) filled in an open-cell metal foam was proposed. Melting experiments in a rectangular cell were ...

Conversion from Shear Creep Compliance to Relaxation Modulus of Asphalt Binder Using Cauchy Residue Method and Experimental Validation
Publisher: ASCE
Abstract: The need for conversion between viscoelastic functions arises in that strain-controlled relaxation test is quite difficult to run than a stress-controlled creep test, especially on rigid sample and at low temperatures. A ...
Current Studies on Seismic Pounding Effect between Adjacent Bridge Decks and Falling-off Prevention Measures
Publisher: American Society of Civil Engineers
Abstract: The recent development of the seismic pounding effect between adjacent bridge decks and falling-off measures were introduced in this paper. Firstly, the computing theories and analytical methods of contact-pounding between ...
Job Burnout of Construction Project Managers: Considering the Role of Organizational Justice
Publisher: American Society of Civil Engineers
Abstract: Construction project managers (CPMs) of contractors experience a great deal of stress. In this study, the authors used job burnout as a core indicator of the chronic psychological stress of CPMs. Based on the job demand-resource ...
Contribution of the Hydroxyl Group on Interfacial Heat Conduction of Monohydric Alcohols: A Molecular Dynamics Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Monohydric alcohols have been used as promising phase change materials (PCMs) for low-temperature latent heat storage. However, the heat storage/retrieval rates are limited due to the low thermal conductivity of such ...
Cotidal Charts near Hawaii Derived from TOPEX/Poseidon Altimetry Data
Publisher: American Meteorological Society
Abstract: armonic analysis of 10 yr of Ocean Topography Experiment (TOPEX)/Poseidon (T/P) along-track altimetry is performed to derive the semidiurnal and diurnal tides (M2, S2, N2, K2, K1, O1, P1, and Q1) near Hawaii. The T/P ...
Development and Experimental Study of a New Rotational Metallic Damper for the Beam–Column Connection
Publisher: ASCE
Abstract: To increase the energy dissipation capacity and deformation capacity of the beam-column connections, and save space for realizing more architectural functions in the frame structure, a new type of metallic damper is developed ...
Propagation Characteristics of Acoustic Emission Waves in Three Different Asphalt Pavement Materials
Publisher: ASCE
Abstract: Due to the differences of physical and mechanical properties of asphalt pavement materials, asphalt pavement (asphalt mixture) presents complex characteristics. To explore the acoustic emission (AE) wave characteristics ...
