Figure 14
The left panel labeled “(a)” and the right panel labeled “(b)” each show a cube with a similar central cavity and smooth curved internal boundaries, overlaid with contour bands representing “P E E Q (Average: 75 percent)”. A vertical color legend beside each cube is shown. In the left panel, it ranges from 0.000 e plus 00 to positive 1.305 e minus 01, with multiple contour levels, from blue (lower), cyan, green, yellow, orange, red, and gray (higher), marked in scientific notation, where the upper cavity edge shows a narrow, sharply curved red and gray band forming a tight arc along the cavity roof, with closely spaced contour lines stacked near the top center, while the side regions contain slightly bulged green and yellow bands that curve inward toward the cavity, and the bottom region shows a deep blue zone with a narrow, elongated shape extending downward from the cavity center. In the right panel, it ranges from 0.000 e plus 00 to positive 1.306 e minus 01, with similar contour levels and color progression, where the upper cavity edge shows a wider red and orange band forming a smoother and flatter arc across the cavity roof with more evenly spaced contour lines, while the side regions display more symmetric green and yellow bands with smoother curvature and less inward bulging, and the bottom region shows a broader blue zone with a wider base and less elongated downward extension compared to the left panel.Contour plots of equivalent plastic strain in the SC porous structure with 5% porosity and of 0.0316, subjected to loading at different applied strain rates: (a) and (b) .
