This article focuses on neural network capture constitutive . On the right of the above figure is the comparison between neural network prediction data and linear constitutive prediction data , Missing experimental data , It's really a pity .

Specifically, neural network is used to capture the constitutive equation , So how to catch it ？

The introduction in the first paragraph is very good ,

These two methods are explained , The method of predicting constitutive law .

The principle is very simple , Let the neural network fit such a model , Mapping a strain state to a stress state .（ See above ）
