RISObserved versus Simulated Second-Moment Climate Statistics in GCM Verification
Publisher: American Meteorological Society
Abstract: The observed and simulated (by the Hamburg GCM) Northern Hemisphere monthly surface air temperatures, averaged within different latitude bands, are statistically analyzed and compared. The objects used for the analysis are ...
Effects of Peeling Stresses in Bimaterial Assembly
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Peeling stress is experimentally shown to be an important factor for delamination in thermally mismatched bimaterial assembly. Strips of the plastic ULTEM-1000 and nickel alloy Kovar were attached ...
A Conformal Lubricated Contact of Cylindrical Surfaces Involved in a Non-Steady Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A non-steady problem for a conformal elastohydrodynamically lubricated (EHL) contact of two infinite cylindrical surfaces with parallel axes is considered. It takes into account the elasticity of ...
Revision of a Fundamental Assumption in the Elastohydrodynamic Lubrication Theory and Friction in Heavily Loaded Line Contacts With Notable Sliding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analysis of the classic friction modeling in lubricated contacts is conducted. Its major deficiency for soft materials (lowelastic moduli) leading to significant overstating of friction in heavily loaded isothermal and ...
Uniform Equations in the Inlet and Exit Zones of Heavily Loaded Point and Line Elastohydrodynamically Lubricated Contacts Involved in Various Steady Motions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Heavily loaded point elastohydrodynamically lubricated (EHL) contacts involved in steady purely transitional, skewed transitional, and transitional with spinning motions are considered. It is shown that in the central parts ...
Contact Fatigue of Rough Elastic Surfaces in Two-Dimensional Formulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Solution of a contact problem for a rough elastic half-plane is considered. Surface roughness is assumed to be small and stochastic. A perturbation solution of the problem for relatively small ...
Fatigue Modeling for Elastic Materials With Statistically Distributed Defects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper is devoted to formulation and analysis of a new model of structural fatigue that is a direct extension of the model of contact fatigue developed by (2000, STLE Tribol. Trans., 43, ...
Formulation and Analysis of EHL Problems for Soft Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a qualitative and numerical analysis of the new formulation of a steady problem for lubricated rollers made of elastic materials with low Young’s modulus. The feature that ...
The Second-Moment Climatology of the GATE Rain Rate Data
Publisher: American Meteorological Society
Abstract: The first part of this paper presents the description of the GARP (Global Atmospheric Research Program) Atlantic Tropical Experiment 1 rain-rate data and its two-dimensional spectral and correlation characteristics, which ...
Linear versus Self-Sustained Interdecadal Thermohaline Variability in a Coupled Box Model
Publisher: American Meteorological Society
Abstract: Recent studies of decadal/interdecadal climate variability suggested two main classes of mechanisms: self-sustained (supercritical) oscillations due to the internal nonlinearity of the ocean and linear (subcritical) ...
