Figure 13
The horizontal axis at the bottom right is labeled “Displacement (millimeters)” and ranges from 10 to 20 in increments of 2. The horizontal axis at the bottom left is labeled “Force (Newton)” and ranges from 2000 to 7000 in increments of 1000. The vertical axis on the right is labeled “Energy absorption percentage” and ranges from 20 to 90 in increments of 10. Two sets of data points are shown: Black dots labeled “Experiment” and blue dots labeled “Neural network.” The data points are scattered across the plot with multiple sets of both dots. Multiple sets of data points are present at the bottom plane between the displacement of 8 and 14 and between the force of 2000 and 4500. Some of the data points are also positioned at the bottom plane between the displacement of 17 and 21 and between the force of 5500 and 7000. Multiple sets of data points are positioned on the vertical plane at the back side between the energy absorption of 30 and 70 percent and between the force of 2000 and 4500. Note: All numerical data values are approximated.Comparison on FE-guided LM neural network prediction against experimental results
