Problem Description
In this example a twisted cantilever beam, modeled with shell elements, is subjected to unit forces at the tip in the in-plane and out-of-plane directions, that is, the Y and Z directions, respectively. The in-plane and out-of-plane loads are applied in different load cases. The tip displacements in the direction of the load are compared with independent hand calculated results.
The geometry, properties and loading are as suggested in MacNeal and Harder 1985. The cantilever beam is twisted 90° from the root (fixed end) to the tip. It is 12 inches long, 1.1 inches wide and 0.32 inches thick. For modeling in this model the twisted beam is meshed 2x12 (24 area objects total) as shown in the figure.
