An Experimental Study of Liquid Entrainment by Expanding Gas
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study of the hydrodynamic aspect of the expansion process in a hypothetical core disruptive accident (HCDA) by means of a shock-tube technique is described. The working fluid ...
Influence of Alpha Casing on Superplastic Deformation of Ti-6Al-4V
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Impact of alpha casing on the superplastic deformation of Ti-Al-4V was studied by applying an oxygen barrier coating onto the surface prior to superplastic forming and mechanical testing at ...
On the Fragmentation of Drops
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fragmentation of mercury drops falling through a bubbly aqueous liquid by a pressure shock wave was investigated by means of a shock tube capable of operating at driver pressures up to 3 ...
Finite Element Modeling of Superplastic Sheet Metal Forming for Cavity Sensitive Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a constitutive equation for superplasticity, which is based on the microstructural mechanism of superplastic deformation taking into account the effects of deformation damage, is ...
A Model for Convective Boiling in a Narrow Eccentric Annular Gap
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A steady-state model is developed for convective boiling and dryout in an eccentric annulus with line contact between the heated inner wall and the adiabatic outer wall. The geometry and heat ...
Sheet Forming Analysis Based on Improved Contact Searching Algorithm and Simple Approach for Contact Force Evaluation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Explicit finite element procedures for the simulation of sheet-metal-forming processes are reviewed. Improved techniques for contact searching and contact force evaluation are then proposed and ...
Evolutionary Optimization and Use of Neural Network for Optimum Stamping Process Design for Minimum Springback
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sheet metal forming is characterized by various process parameters such as the forming sequence, shapes of products and dies, friction parameters, forming speed etc. A designer is faced with ...
