Abstract
The objective of this work is to provide an operational model for the numerical simulation of the shaping processes by plastic deformation of thin plates made of Titanium alloy. Hence, the importance of developing a general framework of elastoplastic orthotropic models (initial orthotropy and isotropic hardening) based on the choice of an equivalent stress, a law of hardening for the development of a strategy of identification of the model from an experimental database. At this level, the identification of the constitutive parameters involved in the laws of behavior of the materials represents an important step in this work. A new identification strategy accompanied by its validation using the criterion of Barlat will be proposed. Numerical simulation can be a very useful tool for titanium alloy. Mainly due to its use in orthopedic surgery; Titanium is of great interest because of its elasticity modulus very close to that of the bone.
