Characterization and modeling of the elastic behavior of a XC68 grade steel used at high strain rates and high temperatures

Résumé

This article discusses the characterization and modeling of the elastic behavior of a semihard steel used in incremental forming operations which implies great loading speeds at high temperatures and large springback after each passage of the roller. The knowledge of the elastic behavior is essential to correctly predict these springbacks during forming. The objective is therefore on the one hand the characterization of the elastic response of the material under different conditions and on the other hand the definition of a model that describes the material behavior with as much precision as possible. To this end, two models, one phenomenological and the other built on more physical basis, are considered.
