Machine learning-based constitutive model for J2- plasticity

International Journal of Plasticity, 2021
This research aims to propose a machine learning (ML)-based constitutive model to predict elastoplastic behavior for J2-plasticity. An artificial neural network (ANN) was constructed to replace the nonlinear stress-integration scheme conducted in the ...
