# OS-V: 0710 Curved Cantilever Beam

MacNeal-Harder Test This is a curved cantilever beam solved with solid and shell elements. A model is made with each element's type to investigate the effect of distorted elements with a high aspect ratio.

## Benchmark Model

Six types of elements are used for this problem. They are tria-shell, quad-shell, and hexa-solid elements, each with 1st and 2nd order. Two loading cases, in-plane bending and transverse bending, are used for each model. For both load cases, unit loads are applied in a consistent fashion over all of the nodes at the tip of the beam.

Load Type | Component | Value |
---|---|---|

In-plane bending | UY | 0.08734 |

Transverse bending | UZ | 0.5022 |
