RISOn the Role of Different Strain Components, Material Plasticity, and Edge Effects When Predicting Machining-Induced Residual Stresses Using Finite Element Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Finite element modeling (FEM) of machining-induced residual stresses (RS) takes place over two consecutive steps: a cutting step and a relaxation step. In the latter, the workpiece is left to cool down after deactivating ...
Modeling General Hysteresis Behavior and Random Vibration Application
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple constructive technique for the development of rate-type hysteresis models for general nonlinear system is presented. The technique is used to develop hysteresis models to incorporate ...
Water Requirements versus Water Availability in Saudi Arabia
Publisher: American Society of Civil Engineers
Abstract: Water demand in the Kingdom of Saudi Arabia has increased from 1,750 million cubic meters (
Modeling Knowledge for Architectural Programming
Publisher: American Society of Civil Engineers
Abstract: Architectural programming practices are still being perceived to be inefficient. This research endeavors to respond to this concern by proposing a generic framework model that aims at capturing the process of properly ...
Coping with Uncertainty in Environmental Construction: Decision-Analysis Approach
Publisher: American Society of Civil Engineers
Abstract: The environmental-cleanup market offers new and emerging business opportunities for the construction industry. However, these opportunities present substantial risks to contractors that decide to engage in cleaning up ...
Energy and Exergy Analyses of a Power Plant With Carbon Dioxide Capture Using Multistage Chemical Looping Combustion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A thermodynamic model and parametric analysis of a natural gas-fired power plant with carbon dioxide (CO2) capture using multistage chemical looping combustion (CLC) are presented. CLC is an innovative concept and an ...
Effects of Strain Hardening and Initial Yield Strength on Machining-Induced Residual Stresses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Finite element analysis was used in the current study to examine the effects of strain hardening and initial yield strength of workpiece material on machining-induced residual stresses (RS). An ...
Fully Coupled Finite-Element Modeling of Active Sandwich Panels With Poroelastic Core
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Active sandwich panels are an example of smart noise attenuators and a realization of hybrid active-passive approach for the problem of broadband noise reduction. The panels are composed of ...
A Control Design Approach for TITO Systems Using Measured Data
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the design of fixed-structure controllers for two-input two-output (TITO) systems using frequency-domain data. In standard control approaches, a plant model is first derived, then a suitable controller ...
The Effect of Mean Stress on the Fatigue Behavior of Woven-Roving Glass Fiber-Reinforced Polyester Subjected to Torsional Moments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of torsional mean stress on the fatigue behavior of glass fiber-reinforced polyester (GFRP) is studied by testing thin-walled, woven-roving tubular specimens with two fiber orientations, ...
