Figure 2. Good correlation between LS-DYNA simulations (dashed lines) and measured clear wood data (solid lines) for southern yellow pine in tension parallel to the grain. Graph.

This graph shows ten different lines, five dashed with respective twins solid in nature. The first line is red and depicts 4 percent MC. The second is yellow and depicts 8 percent MC. The third is green and depicts 12 percent MC. The fourth is blue and depicts 18 percent MC while the fifth is black and depicts Saturated. The vertical axis of this graph ranges from 0 to 150 and represents Stress (megapascals) while the horizontal axis of this graph ranges from 0.0 to 1.0 and represents Strain (percent). The red lines run nearly parallel diagonally across the graph, the solid red line stopping at the points of 110 on the vertical axis and 0.65 on the horizontal axis, while the dashed red continues to the points of 115 on the vertical axis and 0.7 on the horiztonal axis where it peaks and then gradually slopes back down to the horizontal axis. The yellow lines run nearly parallel, both to the points of 135 on the vertical axis and 0.85 on the horizontal axis, where the solid yellow line ends and the dashed yellow line gradually slopes back down to the horizontal axis. The green lines run nearly parallel to each other, though the solid green line runs higher on the graph’s plane than the dashed, stopping at the points of 145 on the vertical axis and 0.9 on the horizontal axis, while the green dashed line peaks at the points of 140 on the vertical axis and 0.925 on the horizontal axis and then gradually slopes back down to the horizontal axis. The blue lines run nearly parallel, with the solid blue line overextending the blue dashed line, stopping at the points of 130 on the vertical axis and 1.25 on the horizontal axis while the dashed blue line peaks at the points of 125 on the vertical axis and 0.875 on the horiztonal axis where it gradually slopes back down to the horiztonal axis. Finally, the black lines run parallel to each other for only a fraction, the solid black line curving while the dashed black runs straight across the graph. The solid black line curves to the points of 65 on the vertical axis and 0.865 on the horizontal axis while the dashed black line peaks at the points of 85 on the vertical axis and 0.665 on the horizontal axis where it gradually slopes back down to the horizontal line.
