Figure 3
The horizontal axis is labeled “G subscript int [megapascal]” plotted on a logarithmic scale ranging from 10 to the negative 4 power to 10 to the 4 power with the multiples of 10. The vertical axis ranges from 0 to 1 with an interval of 0.2. Three curves are plotted. A solid curve labeled “eta” starts near 0 at the left end of the axis and remains flat and increases gradually, then rises sharply between 10 to the power of 0 and 10 to the power of 1, approaching a value close to 1 and runs horizontally towards the end at the top right. A second curve labeled “Normalized h subscript sigma” is shown with circular markers. It begins around 0.61 at the left side, remains relatively flat at lower G subscript int values, then increases steadily, reaching values close to 1 near 10 to the 2 power and remaining near 1 toward the right. A third curve labeled “Normalized h subscript w”, also with circular markers, starts slightly lower than the previous curve near about 0.55, remains nearly constant at low G subscript int values, then increases more gradually, following a similar upward trend and approaching 1 at higher G subscript int values. Text near the bottom left reads “Layered limit (abs)”, while near the bottom right it reads “Monolithic limit (full)”. On the bottom right side of the curve, text reads “Monolithic limit h subscript w equals 13.92 millimeters, h subscript sigma equals 13.92 millimeters”.
