Résumé

This paper deals with the study of texture evolution during deep drawing tests. The aim of these tests is to obtain the whole range of deformation paths encountered in real industrial processes. Nakazima tests are carried out in order to obtain deformation states ranging from simple tension to equibiaxial stretching. Shear tests are also achieved in a simple shear setup developed for this work. The experimental strain fields are determined accurately with an optical measurement system based on the correlation of digital images. Texture measurements were carried out for the undeformed material and after each test. The texture evolution is compared to the texture obtained from an elastic-plastic rate-independent polycrystalline material model recently developed. Boundary conditions applied in the model reproduce the in-plane stretching of the material with an out-of-plane stress relaxation procedure in order to reach plane stress conditions.
