RISMechanical Analysis of Ultrasonic Bonding for Rapid Prototyping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ultrasonic bonding of thin foils has been recently introduced to rapid prototyping of complex-shaped and/or internally structured layered parts. This article provides the mechanical analysis of ...
Structural Reliability Analysis Using Generalized Distribution Reconstruction Method with Novel Improvements
Publisher: American Society of Civil Engineers
Abstract: The probability density function (PDF) of structural responses is one of the significant fundamentals for structural reliability analysis. Nonetheless, it is still challenging to compute the PDF, especially when the ...
Interior Humidity of Concrete under Dry-Wet Cycles
Publisher: American Society of Civil Engineers
Abstract: The dry-wet cycle is one of the aggressive environmental conditions suffered by concrete. This paper focuses on the experimental study and theoretical simulation of water distribution in normal- and high-strength concrete ...
Effects of Water-Binder Ratio and Coarse Aggregate Content on Interior Humidity, Autogenous Shrinkage, and Drying Shrinkage of Concrete
Publisher: American Society of Civil Engineers
Abstract: Experimental studies on shrinkage and interior humidity of three series of concrete with three aggregate contents in each concrete under sealing and drying conditions were carried out. The results show that the development ...
Calculation of Shrinkage Stress in Early-Age Concrete Pavements. II: Calculation of Shrinkage Stress
Publisher: American Society of Civil Engineers
Abstract: This paper focuses on modeling of the shrinkage stress in concrete pavements that experience nonlinear shrinkage strain through the depth of the slab. A closed form of an analytical solution of shrinkage stress is developed. ...
Calculation of Shrinkage Stress in Early-Age Concrete Pavements. I: Calculation of Shrinkage Strain
Publisher: American Society of Civil Engineers
Abstract: This paper focuses on modeling of the distribution of shrinkage strain in early-age concrete pavements. In the modeling, an integrative model for autogenous and drying shrinkage predictions of concrete at an early age is ...
Experimental Analysis of Chloride Penetration into Concrete Subjected to Drying–Wetting Cycles
Publisher: American Society of Civil Engineers
Abstract: To clarify the mechanism of chloride penetration into concrete subjected to drying–wetting cycles, two kinds of concrete, ordinary portland cement concrete and fly ash (FA) concrete, were tested in a cyclic NaCl solution ...
Interior Relative Humidity of Normal- and High-Strength Concrete at Early Age
Publisher: American Society of Civil Engineers
Abstract: The moisture content in the concrete pores is a critical parameter for most of the degradation processes suffered by concrete, for example concrete shrinkage and related cracking. In the present paper, the development of ...
Utilizing Recycled Clay Brick Powder to Improve the Dispersivity and Water Stability of Dispersive Soil: A Sustainable Soil Improvement
Publisher: American Society of Civil Engineers
Abstract: Dispersive soil is susceptible to water erosion and could cause damage in geotechnical engineering or hydraulic engineering projects. Recycled clay brick powder (RCBP) was used as a modifier to improve the dispersivity and ...
Study of Heat–Mass Transfer and Salt–Frost Expansion Mechanism of Sulfate Saline Soil during the Unidirectional Freezing Process
Publisher: American Society of Civil Engineers
Abstract: The water and salt movement and crystallization deformation of saline soil in cold and arid regions is a complex hydrothermal–salt–mechanical coupling problem. Based on the law of mass conservation, the law of energy ...
