Benchmark from MacNeal (1985)
In this document we compare results produced by Ashes to results published in the paper by
Macneal et al. (1985)
, who propose different static tests on cantilever beams to verify Finite Element code. The models proposed are created in Ashes, and a dynamic simulation is performed. If the displacement of the tip of the beam at the end of the simulation match the values of
Macneal et al. (1985)
, the tests are considered passed.
Table 3 from
Macneal et al. (1985)
, which contains the theoretical results used in this benchmark, is reproduced here:
| Load case | Displacement in the direction of the load [m] | ||
