Parameter Estimation
How to tame a vast number of combinations
use A I to learn material properties for e.g.
- spotwelds with different material combinations
- composites with different fiber or matrix materials

check model validity

analyzing input space
Your model parameters look perfect, but is your model valid within your load case?
- find sparse areas where no experimental data exist
- check if your simulation result is covered by experimental data
use unsupervised learning methods
