The simple shear test has been studied extensively in recent decades. The main reason is that it can easily be achieved on a conventional tensile machine using a suitable device. This work presents the evolution of shear characterization over the years and its use for the characterization of anisotropic elastoplastic constitutive laws for metallic sheets. From the first tests and numerical simulations carried out in 1989, to the development of several generations of shearing machines, to the use of DIC for the strain measurement via the characterization of the Portevin Le Châtelier effect and that of ultrafine sheets for the identification of crystal plasticity models, this work analyzes tests carried out on several materials (steels, aluminum alloys, alloys of copper) and show that this test is particularly adapted to the characterization of various elastoplastic constitutive laws.
