Development of a Neural Network Simulator for Studying the Constitutive Behavior of Structural Composite Materials

Figure 5

One of the 500 (𝐽) training testing results showing that W-fiber elastic strain and composite total strain are perfectly matched between target FEM and trained ANN. This kind of stress/strain data (for entire output nodes, 𝑀) can be directly monitored via the test data monitor mode in the GUI. The 𝑅² values of all the test data are greater than 0.999. The negative sign indicates the compression mode in loading and deformation.
