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 ...
Clumpy disc and bulge formation
(Wiley-blackwell Publishing, Inc, 2013-11)
We present a set of hydrodynamical/N-body controlled simulations of
isolated gas-rich galaxies that self-consistently include supernova (SN)
feedback and a detailed chemical evolution model, both tested in
cosmological ...
Chemical evolution of the Galactic bulge as traced by microlensed dwarf and subgiant stars IV. Two bulge populations
(EDP SCIENCES S A, 2011)
Based on high-resolution (R approximate to 42 000 to 48 000) and high signal-to-noise (S/N approximate to 50 to 150) spectra obtained with UVES/VLT, we present detailed elemental abundances (O, Na, Mg, Al, Si, Ca, Ti, Cr, ...
Constitutive modelling of the mechanical response of a polycaprolactone based polyurethane elastomer: Finite element analysis and experimental validation through a bulge test
(Professional Engineering Publishing Ltd, 2021-05)
The mechanical behaviour of a high performance polycaprolactone based polyurethane elastomer (PCL) up to large strain levels, cyclic loading and equibiaxial stress has been assessed. The PCL can be categorised as a rubber-like ...
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 ...
PLANETARY NEBULAE IN THE INNER MILKY WAY II: THE BULGE-DISK TRANSITION
(UNIV NACIONAL AUTONOMA MEXICO, INST DE ASTRONOMIA, 2011)
In this work, a sample of planetary nebulae located in the inner-disk and bulge of the Galaxy is used in order to find the galactocentric distance which better separates these two populations, from the point of view of ...
Planetary nebulae and determination of the bulge-disk boundary
(International Astronomical UnionBeijing, 2012)
In this paper, a sample of planetary nebulae in the Galaxy's inner-disk and bulge is used to find the galactocentric distance that optimally separates these two populations in terms of their abundances. Statistical distance ...

Is Terzan 5 the remnant of a building block of the Galactic bulge? Evidence from APOGEE
(Oxford University Press, 2022-07-01)
It has been proposed that the globular cluster-like system Terzan 5 is the surviving remnant of a primordial building block of the Milky Way bulge, mainly due to the age/metallicity spread and the distribution of its stars ...
