The determination of limit loadings that induce strain localization during material forming operation is always an important industrial concern, especially when it appears during the forming operation during which the material is highly stressed. Several recent studies have demonstrated that the intrinsic structural heterogeneity of metallic materials plays an important part in their mechanical behavior. Nevertheless, the role of heterogeneities on strain localization is not yet really broached. The objective of this study is to determine if the structural heterogeneity of materials has an impact on the localization of ductile materials. A corollary action is then to validate the use of models that integrate this heterogeneity to achieve better results. The study is composed of two parts: experimental and numerical. Concerning the experimental part, in order to obtain different degrees of heterogeneities, titanium samples were prepared to have materials with structure hexagonal and cubic centered which pr...
