RISEvaluating the <i>N<sub>γ</sub></i> Coefficient for Shallow Strip Footings on Sloping Ground by the Method of Stress Characteristics
Publisher: ASCE
Abstract: This study presents a new solution algorithm to calculate the bearing capacity coefficient Nγ for a fully rough strip footing located on an infinite slope considering different soil friction angles φ and ground slopes β° ...
Nonlinearity Measure for Nonlinear Dynamic Systems Using a Multimodel Framework
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article is concerned with the assessment of nonlinearity in nonlinear dynamic systems to determine the feasibility of controlling a nonlinear system with either a single linear controller or a multimodel controller. ...
Experimental Study of a New Flow Conditioner on Disturbed Flow in Orifice Plate Metering
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The sensitivity to poor conditioned and swirling flow of flow measurements using an orifice plate are subjects of concern to flowmeter users and manufacturers. Measurements of mass flow rate ...
A Perturbation Method for Studying Heat Conduction in Solid With Random Conductivity
Publisher: The American Society of Mechanical Engineers (ASME)
Bounds on Earthquake Response of Structures
Publisher: American Society of Civil Engineers
Abstract: Dynamics of an elastic structure subjected to simultaneous horizontal and vertical earthquake ground accelerations are considered. The Liapunov method is used and several general bounds on the maximum responses are developed. ...
Output-Only Modal Analysis of Micromilling Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An output-only modal analysis (OMA) approach is presented to obtain the direct frequency response function (FRF) at the tip of the tool in micromilling setups. White noise input is provided using acoustic excitation and ...
Comprehensive Investigations of the Effect of Bolt Tightness on Axial Behavior of a MERO Joint System: Experimental, FEM, and Soft Computing Approaches
Publisher: ASCE
Abstract: In the present experimental study, 12 specimens were tested to assess and quantify the effects of bolt tightness on the overall behavior of a bolt-ball joint under uniaxial loading. A three-dimensional (3D) nonlinear ...
A New Structured Multimodel Control of Nonlinear Systems by Integrating Stability Margin and Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with a new systematic multimodel controller design for nonlinear systems. The design of local controllers based on performance requirements is incorporated with the concept of local models selection as an ...
Investigations on Impulse Blade Cascades with Medium Deflection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The transformation of energy in the stages of high-reaction axial compressors can be considerably increased if the rotor blading consists of tandem cascades. This also involves aerodynamically ...
Effects of Microhydrophobic Porous Layer on Water Distribution in Polymer Electrolyte Membrane Fuel Cells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Performance of polymer electrolyte membrane fuel cells (PEMFC) at high current densities is limited to transport reactants and products. Furthermore, large amounts of water are generated and may be condensed due to the low ...
