Figure 1 shows a Z-shaped cantilever laid along the oblique line of 45°. The total load P at all the points on the free end D in the positive Z-direction is conservative (non-follower load). The cantilever structure is modeled using bar or quadrilateral shell elements. Tension stiffening and the change in sign of bending moment can be observed.
