RISPrediction of Plastic Wrinkling Using the Energy Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The prediction and prevention of wrinkling during a sheet metal forming process have been challenging issues on the design of part shape, die geometry, and processing parameters. In an effort ...
A Predictive Tool for Delaying Wrinkling and Tearing Failures in Sheet Metal Forming
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the sheet metal forming industry, there is increasing demand to lower manufacturing costs while also providing a decrease in product development turnaround period as well as lighter weight ...
Numerical and Experimental Studies of Oscillatory Airflows Induced by Rotation of a Grass-Cutting Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three-dimensional oscillatory airflows induced by a rotating grass-cutting blade in a cylindrical chamber are studied experimentally and numerically in this paper. Experimental pressure results are ...
Optimal Cool-Down in Linear and Nonlinear Thermoviscoelasticity and the Effects of Initial Stress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article concerns the minimization of residual thermal stresses in geometrically constrained adhesive layers and thin polymeric composite lay-ups with emphasis on the role of initial stresses. ...
Large Eddy Simulation of Turbulent Axial Flow Along an Array of Rods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Large eddy simulation (LES) is employed in this paper to model the axial flow along a circular array of rods with a focus on anisotropic large-scale turbulence. The circular array consists ...
Accommodation of Springback Error in Channel Forming Using Active Binder Force Control: Numerical Simulations and Experiments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Springback in a forming process is due to the elastic deformation of the part during unloading. This manufacturing defect can be accounted for through proper tooling design or through proper ...
Modeling an Integral Dual Solar/Gas-Fired Generator for a Water-Lithium Bromide Absorption Chiller
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a design procedure for a dual solar/gas-fired generator of an absorption chiller. The solar energy is the primary driving source for the generator, while the natural gas ...
Study of Dimensional Repeatability and Fatigue Life for Deformation Machining Bending Mode
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Deformation machining (DM) is a hybrid process which combines two emerging manufacturing processes, machining of thin structures and single-point incremental forming (SPIF). This hybrid process ...
Design Guidelines for Longitudinal Plate to HSS Connections
Publisher: American Society of Civil Engineers
Abstract: Although longitudinal plates have been used widely to connect braces and other attachments to hollow structural sections (HSS), there is no established design method available for this type of connection. Research work has ...
Measuring Retardation Factors of Cesium133 and Strontium88 Cations Using Column Test
Publisher: American Society of Civil Engineers
Abstract: A flow-through column test setup was developed to measure the breakthrough curves of cesium133 (Cs) and strontium88 (Sr) cations in a natural silty sand. Advantages of this column setup include ensuring full saturation ...
