SAE Keyhole
This example is a benchmark based on the Altair eFatigue SAE Keyhole example. The test and analysis is original found in the book "Fatigue Under Complex Loading: Analysis and Experiments", Advances in Engineering, AE-6, Society of Automotive Engineers, Warrendale, PA, R.M.Wetzel Editor, 1977.
In this example the listed features in SimFat are used (but not limited to):
- FE model from PTC Creo Simulate (2D plane stress thin plate)
- Unit load (1kN load applied)
- Load history are a created based on FE unit load
- Custom SN evaluation method (Custom SN)
- A single cycle load
Example details
This example is simplified to the fully reversed load case of -13.3kN and 13.3kN that together is the oné fatigue load cycle. And the example only look at the material RQC-100. The geometry reated with PTC Creo Parametric and the FE model is created with PTC Creo Simulate. The geometry is simplified to a 2D plane stress example. (The model could have been reduced to a symmetric model)
