Implicit constitutive modelling for viscoplasticity using neural networks. (English) Zbl 0926.74020
We define an implicit constitutive model and propose an implicit viscoplastic constitutive model using neural networks. In tour modelling, inelastic material behaviours are generalized in a state-space representation, and the state-space form is constructed by a neural network using input-output data sets. We also describe a technique to extract the input-output data from experimental data.
