Strain and strain rate measurement during the Bulge Test by electronic speckle pattern interferometry
Journal of Materials Processing Technology, 2007Co-Authors: Guillaume Montay, Manuel François, Marie Tourneix, Bruno Guelorget, Cristián Vial-edwards, Ignacio LiraAbstract:Abstract 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 measure the field of strain increment. The strain rate is used to detect heterogeneity in the strain distribution. The main originality of this work is the application of an optical interferometer to determine the field of plastic strain increments and strain rates in the region of the top of the specimen.

Strain Localization Analysis by a Combination of the Espi With a Bulge Test
Experimental Analysis of Nano and Engineering Materials and Structures, 2007Co-Authors: Guillaume Montay, Manuel François, Marie Tourneix, Bruno Guelorget, Ignacio Lira, Cristián Vial-edwardsAbstract:The problem of strain localization is important in sheet metal forming, as it determines the forming limit diagram of the material. To analyze this process, engineers use a variety of Tests. One of them is the Bulge Test. In it, an initially flat specimen is placed between a matrix and a blank holder, and hydraulic pressure is applied on one of its surfaces. An approximately equi-biaxial strain loading path is obtained [1,2].

Analysis of plastic strain localization by a combination of the speckle interferometry with the Bulge Test
Optics and Lasers in Engineering, 2007Co-Authors: Guillaume Montay, Manuel François, Marie Tourneix, Bruno Guelorget, Cristián Vial-edwards, Ignacio LiraAbstract: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 localization is important in the sheet metal forming processes. The ESPI technique is used to have a better resolution on the measured strains (10−5) than other technique such as the image correlation (10−2, 10−3). The Bulge Test is currently used to determine the mechanical properties of materials by measuring the deformation that occurs in response to the application of a controlled pressure. This Test is used to determine the mechanical properties of sheet metals submitted to an equi-biaxial loading path, the strains at failure are used as data to determine forming limit diagrams (FLDs). The aim of this study is to detect the localization of plastic strain (diffuse and localized necking) during the Bulge Test combined with a common speckle interferometer. This paper describes an original technique to detect the localization using the strain rate at different positions on the sample. The main originality of this work is the application of an optical interferometer to determine the field of plastic strain increments and strain rates in the region of the top of the specimen, at various stages of global strains.
