RISSpectral-Element Method for Levy-Type Plates Subject to Dynamic Loads
Publisher: American Society of Civil Engineers
Abstract: Spectral-element method (SEM) is applied for the vibration analysis of the Levy-type rectangular plates subject to distributed dynamic loads. In the solution procedure, both FFT and inverse FFT computer algorithms are ...
Numerical Search of the Optimum Curing Regimes for High-Early-Strength Concrete
Publisher: ASCE
Abstract: High-early-strength concrete (HESC) made of Type III cement attains approximately 60%–70% of its design compressive strength at ambient temperature in 1 day. A numerical method incorporating a rate-constant model was ...
Theoretical Translation of Clean Water to Wastewater Oxygen Transfer Rates
Publisher: ASCE
Abstract: In wastewater treatment design, it is common practice to test aeration equipment in clean water first, and then extrapolate the result to wastewater via a correction factor. In addition to the many variables, such as the ...
Temperature Correction for Clean-Water Tests with Reference to ASCE/EWRI Standard 2-22
Publisher: ASCE
Abstract: In wastewater treatment design, it is common practice to test aeration equipment in clean water first, and then extrapolate the result to wastewater via a correction factor. The most commonly adopted procedure for testing ...
The Oxygen Transfer Model Applied to Steady-State Respiring Systems
Publisher: American Society of Civil Engineers
Abstract: Up to now, only limited data are available on the influence of process-related variables [influent characteristics, solids retention time (SRT), hydraulic retention time (HRT), biomass recirculation rates, process ...
Enhancing Pullout Load Capacity of Helical Anchor in Clay with Adjusted Load Application Point under Inclined Loading Condition
Publisher: ASCE
Abstract: In this study, the effect of load application point (zp) on the load capacity (Qu) of helical anchors under inclined loading condition was investigated. For this purpose, coupled Eulerian-Lagrangian finite element analyses ...

The Nature of Chip Formation in Orthogonal Machining
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Orthogonal machining experiments were conducted at the cutting speed of 8.5 × 10−2 cm/s with 6061-T6 aluminum, 4340 steel and Ti-6Al-4V titanium to measure strain distributions in the ...
Testing of the Tropically Excited Arctic Warming Mechanism (TEAM) with Traditional El Niño and La Niña
Publisher: American Meteorological Society
Abstract: y analyzing El Niño and La Niña composites with 40-yr European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-40) data, evidence is presented here that the surface air temperature of the Arctic winter ...
A Theory of Continuum Damage Mechanics for Anisotropic Solids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper develops a fracture mechanics based continuum damage theory for initially anisotropic solids by extending the author’s previous damage theory for isotropic solids. The concepts of ...
