The forming of AISI 409 sheets for fan blade manufacturing
(Amer Inst Physics, 2007-01-01)
The necessity of adapting the standardized fan models to conditions of higher temperature has emerged due to the growth of concern referring to the consequences of the gas expelling after the Mont Blanc tunnel accident in ...
Nonlinear electrostatic instabilities in the solar wind
(Blackwell Publishing Ltd, 2009)
It is well known that nonlinear electrostatic instabilities can be triggered in a plasma with streaming ion species in the presence of finite-amplitude Alfvén cyclotron waves. The instability occurs when the phase velocity ...
Strain and strain rate measurement during the bulge test by electronic speckle pattern interferometry
(ELSEVIER SCIENCE SA, 2007)
This paper presents a new experimental method to measure the strain increment and the strain rate during the bulge of a copper sheet. The electronic speckle pattern interferometry (ESPI) is combined with the bulge test to ...
Analysis of plastic strain localization by a combination of the speckle interferometry with the bulge test
(ELSEVIER SCI LTD, 2007)
The process of localization of strains, diffuse and localized necking, up to fracture in equi-biaxial loading was analyzed through the images obtained by electronic speckle pattern interferometry (ESPI). The problem of ...
Theoretical approach including friction for determining strain limits in punch stretching of anisotropic sheet metals
(2010-12-01)
A new analytical theory including friction was developed to assess strain limits in punch stretching of anisotropic sheet metals. This new approach takes into consideration the anisotropic behaviour of sheet materials and ...
