A Neural Network-integrated Elastoplastic Constitutive Model using Haigh–Westergaard Coordinates and Data Augmentation

This study introduces an elastoplastic constitutive model integrated with a neural network, utilizing Haigh–Westergaard coordinates and a data augmentation technique to enhance the prediction of material behavior under monotonic and cyclic loading conditions. The neural network employs the stress of...
