Coefficients of an ANN constitutive flow law of a Ti6-Al-4V material for dynamic applications

This paper gathers the results concerning the identification of the coefficients of the flow law of a Ti6-Al-4V for a flow law defined by a neural network as described and defined by Pantalé et al. This ANN allows the calculation of the flow stress as a function of the plastic strain, the plastic strain rate and the temperature respectively. The method for defining the ANN flow law is not described in this paper, only the identification of the coefficients for a Ti6-Al-4V is part of this paper
