Abstract: This paper is a review of the recently developed inverse strategy combined with finite element simulation to identify the constitutive parameters describing the plastic behavior of metal plates. It emphasizes that the identification procedure depends on the loading conditions, the sample geometry, the type of experimental results selected for analysis, the cost function and the optimization algorithm used. In addition, the type of constitutive relationship (isotropic and or kinematic hardening relationship and or anisotropic yield criterion) to identify its parameters will affect the whole identification process.
