Problem Description
In this example a curved 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 bent into a 90° arc. It has a 4.12 inch inner radius and a 4.32 inch outer radius. Thus it is 0.2 inch wide and approximately 6.63 inch long at its centerline. The beam is 0.1 inch thick in the Y direction. For modeling in this model, the curved beam is meshed into six area objects, each subtending a 15° arc.
