Figure 45. The default number of plasticity algorithm iterations is set to one because these static load-deflection curves are insensitive to the number of iterations. Graph.

This graph shows two distinct lines. The first is dotted green and is labeled 5 Iterations while the second is solid pink and is labeled 1 Iteration. The vertical axis of this graph ranges from 0 to 60 and represents Force (kilonewtons) while the horizontal axis of this graph ranges from 0 to 200 and represents Deflection (millimeters). Both lines begin at the points of zero on both the vertical and horizontal axes. The dotted green line rises steeply to where it peaks at the points of 49 on the vertical axis and 50 on the horizontal axis. From there the line slopes downward sporadically to the points of 16 on the vertical axis and 80 on the horizontal axis where it spikes in the slightest to the points of 20 on the vertical axis and 90 on the horizontal axis. The green line then descends irregularly until it exits the graph at the points of 7 on the vertical axis and 200 on the horizontal axis. The pink line runs exact same path at the dotted green line until it reaches its descending points of 20 on the vertical axis and 90 on the horizontal axis. From there the pink line breaks from the green line, descending irregularly and leaving the graph at the points of 5 on the vertical axis and 200 on the horizontal axis.
