RISNonlinear Seismic Assessment of Concrete Dams Using a Novel Elastoplastic Damage Numerical Framework
Publisher: American Society of Civil Engineers
Abstract: Numerical simulations were conducted to investigate the damage modes of concrete dams under seismic loading. The employed numerical model is based on an elastoplastic damage numerical framework for concrete, which innovatively ...
Mechanism and Kinetics of Pyrolysis of Coal With High Ash and Low Fixed Carbon Contents
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There are much coal with low content of volatile matter (Vad < 20%), high content of ash (Aad > 50%), low heating caloric (∼10,000 kJ/kg) in China. It is very important to study ...
Effect of Spring Precipitation on Summer Precipitation in Eastern China: Role of Soil Moisture
Publisher: American Meteorological Society
Abstract: AbstractThe relation of spring (March?May) to summer (July?August) precipitation in eastern China is examined using observed data. It is found that when spring precipitation from the lower and middle reaches of the Yangtze ...
Nonlocal Shear Deformable Shell Model for Post-Buckling of Axially Compressed Double-Walled Carbon Nanotubes Embedded in an Elastic Matrix
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Buckling and post-buckling analysis is presented for axially compressed double-walled carbon nanotubes (CNTs) embedded in an elastic matrix in thermal environments. The double-walled carbon nanotube ...
Flexural Torsional Guided Wave Mechanics and Focusing in Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Theoretical work on flexural torsional guided waves in pipe is presented along with angular profile experimental justification. Combined with previous work on flexural longitudinal modes and ...
Form-Finding of Nonregular Tensegrity Systems
Publisher: American Society of Civil Engineers
Abstract: The potential applications of tensegrity structures are not only increasing in civil engineering but also in fields like biomechanics. The key step in designing tensegrity, the form-finding problem, has been investigated ...
In-Fire and Postfire Safety Evaluation of Hangers of a Long-Span Suspension Bridge in a Truck Fire Accident
Publisher: ASCE
Abstract: Fire accidents often pose severe threats to the safety of steel bridges. This paper presents the numerical study of the Runyang Suspension Bridge (RSB) fire accident with an emphasis on its in-fire thermal effect on the ...
Analytical and Experimental Characterization of Bonding Over Active Circuitry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Placing active circuitry directly underneath the bond pads is an effective way to reduce the die size, and hence to achieve lower cost per chip. The main concern with such design is the ...
High Frequency Guided Wave Natural Focusing Pipe Inspection With Frequency and Angle Tuning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When ultrasonic guided wave nondestructive evaluation is used to inspect pipelines, partial loading of transducers around the circumference leads to a non-axisymmetric energy distribution. At ...
Effect of Suspended Solids on the Sequential Disinfection of Secondary Effluent by UV Irradiation and Chlorination
Publisher: American Society of Civil Engineers
Abstract: The synergistic effects of sequential ultraviolet (UV) radiation and chlorination on tailing during disinfection of
