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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
