The Use of genetic algorithm and neural network to predict rate-dependent tensile flow behaviour of AA5182-O sheets
TL;DR: In this article, the tensile flow behavior of AA5182-O sheet was experimentally obtained in different material directions (RD, DD, and TD) at strain rates ranging from 0.001 to 1000 s − 1 and predicted by means of both phenomenological models and neural networks (NNs).
