RISAveraging Models for Heterogeneous Viscoplastic and Elastic Viscoplastic Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Averaging models are proposed for viscoplastic and elastic-viscoplastic heterogeneous materials. The case of rigid viscoplastic materials is first discussed. Large deformations are considered. A ...
The Stability of Steady Fronts and the Adjoint Method: Nonmodal Frontal Waves
Publisher: American Meteorological Society
Abstract: The adjoint method for finding optimal or singular modes is employed for studying the finite time stability of steady, tw0-dimensional atmospheric fronts as represented by the uniform potential vorticity semigeostrophic ...
Simulating Disturbances in GPS by Continuous Satellite Distribution
Publisher: American Society of Civil Engineers
Abstract: Rough error estimations of positioning are considerably simplified by taking continuous satellite observation distributions into account. Forming normal equations by integration allows explicit calculations of the effects ...
A CAD/CAM Representation Model Applied to Tolerance Transfer Methods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the adaptation of tolerance transfer techniques to a model called TTRS for Technologically and Topologically Related Surfaces. According to this model, any three-dimensional ...

Semiempirical Model for the Reliability of a Matched Filter Frequency Estimator for Doppler Lidar
Publisher: American Meteorological Society
Abstract: The author proposes a heuristic semiempirical model for predicting the reliability of a matched-filter frequency estimator applied to Doppler lidar signals. The model is tuned by a single coefficient ? empirically related ...
Should Interpolation of Radar Reflectivity be Performed in Z or dBZ?
Publisher: American Meteorological Society
Abstract: AbstractInterpolation of ground-based radar measurements is required when mapping data from their native spherical coordinates to a Cartesian grid. For reflectivity the question arises as to whether this processing should ...
Kinematic and Thermodynamic Study of a Shallow Hailstorm Sampled by the McGill Bistatic Multiple-Doppler Radar Network
Publisher: American Meteorological Society
Abstract: In this paper, the authors examine the kinematic and thermodynamic characteristics of a shallow hailstorm sampled by the McGill bistatic multiple-Doppler radar network on 26 May 1997. This storm consists of two main shallow ...
Development of a Harmonic Balance Method-Based Numerical Strategy for Blade-Tip/Casing Interactions: Application to NASA Rotor 37
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, a frequency-domain approach based on the harmonic balance method coupled to a predictor-corrector continuation algorithm is implemented for the qualitative analysis of blade-tip/casing contacts in aircraft ...
Open NASA Blade Models for Nonlinear Dynamics Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This contribution presents a catalogue of open turbomachinery blade models dedicated to nonlinear dynamics simulations. Based on a specifically developed in-house computer code, three-dimensional computer-aided design (CAD) ...
