Abstract
This paper presents a shearing experiment of sheet metals in order to obtain experimental data at large strain and at high strain rates. Previous studies in the domain were more focused at the shearing loading and criterion aspect so that they looked more at the small strain range. Our interest in this kind of test is in the large strain range so that the analysis of the test may be quite different. For this purpose, the local measurement of strain field by means of the image correlation method is used to evaluate the strain homogeneity and deviation from the pure shear condition when the nominal shear becomes more and more important. Numerical simulations (under ls-dyna) are also made to study the stress state and its homogeneity in large shear of sheet metals.
