RISMaterial Constitutive Law for Large Strains and Strain Rates
Publisher: American Society of Civil Engineers
Abstract: This note comments on a strain rate pattern found in tensile tests. This strain rate pattern readily suggests that the Cowper-Symonds equation relating the static and dynamic flow stresses with the strain rate is not valid ...
Discussion of “Generalized Flow Rating Equations at Prototype Gated Spillways” by Matahel Ansar and Zhiming Chen
Publisher: American Society of Civil Engineers
Dynamic Elastic-Plastic Buckling of Structural Elements: A Review
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Structural elements, which deform inelastically, are often used in energy-absorbing devices due to their simple design and the high efficiency achieved by several buckling deformation mechanisms. ...
On the Relaxation Time Scales of the Classical Thermodynamic Model for Heat Transfer in Quiescent Compressible Fluids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An approximate solution of the classical thermodynamic model for compressible heat transfer of a quiescent supercritical fluid under microgravity leads to the wellknown piston effect relaxation time tPE=tD/(خ³0−1)2, where ...
Experimental Characterization of Noise Sources for Duct Acoustics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many industrial applications involving the acoustics of ducting or piping systems require an improved description of noise sources, so that a better prediction and evaluation of system performance ...
Indian Ocean Variability and Its Association with ENSO in a Global Coupled Model
Publisher: American Meteorological Society
Abstract: The evolution of the Indian Ocean during El Niño?Southern Oscillation is investigated in a 100-yr integration of an Australian Bureau of Meteorology coupled seasonal forecast model. During El Niño, easterly anomalies are ...
An Ensemble Ocean Data Assimilation System for Seasonal Prediction
Publisher: American Meteorological Society
Abstract: A new ensemble ocean data assimilation system, developed for the Predictive Ocean Atmosphere Model for Australia (POAMA), is described. The new system is called PEODAS, the POAMA Ensemble Ocean Data Assimilation System. ...
Intraseasonal Forecasting of the 2009 Summer and Winter Australian Heat Waves Using POAMA
Publisher: American Meteorological Society
Abstract: xtreme heat waves occurred over much of southern and eastern Australia during the summer (27 January?8 February) and winter (14?31 August) of 2009. The summer heat wave resulted in many temperature records across southeastern ...
Progress in Electronic Control of Large Diesel Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The general theme of the growing use of electronic systems for the control and monitoring of large diesel engines is discussed. Central to the theme is a new digital governing system for ...
Prediction of Vibrations and Reradiated Noise Due to Railway Traffic: A Comprehensive Hybrid Model Based on a Finite Element Method and Method of Fundamental Solutions Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The growing of railway infrastructures in urban environments demands accurate methods to predict and mitigate potential annoyance of the inhabitants of the surrounding buildings. The present paper aims to contribute to the ...
