Stress behavior can be viewed only in a particular state. The red color at Fringe Levels in Fig. 1 shows a maximum value of stress in GPa. It can be seen that the most severe in terms of stress (indicated by red in Fig. 1). Therefore, in both contour display, red color in the fringe levels represents the most vulnerable part in the simulation contour, while blue color represents the most durable part. In contrast to von-Mises stress, stress on the x, y, and z axes have a negative sign on the stress value, which indicates that the direction of the stress is opposite to the axis direction. Then, the red contour represents the maximum stress value in the observed axes, as shown in Figs. 2 to 4.
