8.20 Surfaces - Other Stresses
To control the graphical display of stress components due to bending moments and membrane forces, select Surfaces → Stresses in the Results navigator (see Figure 8.48). Table 4.20 shows these stresses in numerical form.
The table shows the other stresses sorted by surfaces. The results are listed in reference to the grid points of each surface.
The numbers of the grid points are listed by surfaces. For more information about grid points, see Chapter 8.13.
Table columns B to D show the coordinates of grid points in the global coordinate system XYZ.
The stresses are related to the directions of the local surface axes. When you analyze curved surfaces, they refer to the axes of the finite elements (see Figure 8.41).
The stresses have the following meanings:
Stress due to bending moment mx
Stress due to bending moment my
Stress due to torsional moment mxy
Membrane stress due to axial force nx
Membrane stress due to axial force ny
Membrane stress due to shear flow nxy
