Figure 7
The left panel labeled “(a)” and the right panel labeled “(b)” each show a cube with different smooth curved cutouts, overlaid with contour bands representing “U, U 1”. A vertical color legend beside each cube is shown. In the left panel, the cube has a prominent curved cutout at the bottom front edge and a smoother curved surface near the top, with contour levels ranging from negative 1.267 e minus 03 to positive 0.000 e plus 00, displayed from purple (lower), blue, cyan, green, yellow, orange, to red (higher), where higher value bands are concentrated along the left face and lower left regions, while lower values dominate the right face, with contour lines bending around the curved geometry. In the right panel, the cube shows a differently positioned curved cutout along the upper left and right corners and another along the bottom front region, with contour levels ranging from negative 1.266 e minus 03 to positive 0.000 e plus 00, following the same color progression, where higher value bands appear along the left and top surfaces, and values decrease toward the right face and around the cutouts, forming smooth gradients with contour lines adapting to the altered geometry. The differing cutout positions in each panel change the contour distribution patterns locally, especially near edges and corners. A coordinate axis indicator between the panels shows directions labeled “X”, “Y”, and “Z”.Contour plots of lateral displacement along the x-direction (in mm) in the (a) BCC and (b) FCC structures at 15% porosity. The applied overall displacement in the y-direction is at 0.005 mm (within the elastic limit)
