• The main idea of this paper is to improve our knowledge on localization in a specific case of heterogeneous materials: strips with both aluminium and steel in thickness. A characterization of each material separately has been done by tensile test and also by plane strain tensile test. Afterwards, these two tests are studied on the bimaterial. This study is both experimental with digital image stereo-correlation for strain measurements on both side (aluminium and steel) and numerical with a finite element simulation. A better understanding of the behaviour of a bimaterial can be deducted: aluminium makes mechanical resistance decrease but reinforces the resistance to localization. Some crossing effects have been revealed what induces a fine analyse for each study involving other configurations of bimaterials.
