Figure 10
The left panel labeled “(a)” and the right panel labeled “(b)” each show a cube with a 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 1.328 e minus 01, with multiple contour levels, from blue (lower), cyan, green, yellow, orange, red, and gray (higher), marked in scientific notation, where higher value bands are concentrated around the upper inner cavity edges, forming tight layered contours, while lower values dominate the lower central region and bottom face, with contour lines wrapping closely around the narrower cavity. In the right panel, it ranges from 0.000 e plus 00 to positive 9.500 e minus 02, with multiple contour levels, from blue (lower), cyan, green, yellow, orange, and red (higher), marked in scientific notation, where higher value bands are distributed along the top surface and upper side regions, while lower values appear in the lower central region. The cavity in the right panel is wider and larger, causing contour bands to spread more broadly with smoother transitions and less tightly packed layers near the opening.Contour plots of equivalent plastic strain in the closed-cell SC porous structure with porosities of (a) 5% and (b) 20%, when the overall applied tensile strain is at 0.05
