Figure 14
The visual consists of two surface contour plots placed side by side, each showing a square plate oriented as a diamond shape with contour shading and a coordinate indicator at the bottom center labeled “X”, “Y”, and “Z”. The X-axis extends towards the lower right, the Y-axis extends vertically upward, and the Z-axis extends towards the lower left side. On the left side, a vertical color scale labeled “S, Max. Principal (Avg: 75 percent)” lists values from top to bottom as positive 2.800 e positive 07, positive 2.567 e positive 07, positive 2.333 e positive 07, positive 2.100 e positive 07, positive 1.867 e positive 07, positive 1.633 e positive 07, positive 1.400 e positive 07, positive 1.167 e positive 07, positive 9.335 e positive 06, positive 7.002 e positive 06, positive 4.669 e positive 06, positive 2.336 e positive 06, positive 2.425 e positive 03, and negative 2.371 e positive 06. The color transitions from red at the top through intermediate shades to dark blue at the bottom. In the left panel, the surface is predominantly dark blue across the central region. A square-shaped lighter region appears at the center, surrounded by thin contour lines forming a diamond-shaped pattern aligned with the plate orientation. Along the edges, a continuous band transitions from blue to red, with the highest values concentrated at the four corners where red regions are most intense. Between the center and edges, thin contour lines form symmetric patterns extending diagonally and horizontally across the plate. On the right side, a vertical color scale labeled “S, Mises (Avg: 75 percent)” lists values from top to bottom as positive 2.800 e positive 07, positive 2.567 e positive 07, positive 2.333 e positive 07, positive 2.100 e positive 07, positive 1.867 e positive 07, positive 1.633 e positive 07, positive 1.400 e positive 07, positive 1.167 e positive 07, positive 9.335 e positive 06, positive 7.002 e positive 06, positive 4.669 e positive 06, positive 2.336 e positive 06, and positive 2.425 e positive 03. In the right panel, the surface is mostly dark blue with a cross-shaped pattern formed by slightly lighter bands extending across the plate along two perpendicular directions. The intersections of these bands form a grid-like structure across the surface. The edges show a continuous band transitioning toward red, with the corners displaying the highest red regions. Additional rounded patches appear between the central and edge regions, forming symmetric patterns distributed across the plate.Detail of maximum principal vs Von Mises stress distribution in the top glass cover (legend values in Pa), based on Figure 11 (ABAQUS).
