1. CEA Validation tests and constraints
What tests can we do to ensure compatibility of the FEA with the real system

2. CAE Parameter Tests for Materials
Material properties & identification
3D Physical performance
3D Coefficient of thermal expansion
3D Hydroscopic swelling
Creep tests
Composite specific tests
Make it into a student project

3. CAE Validation tests for Elements generic plan
Do multiple simple tests throughout the manufacturing process to obtain test cases to validate the FEA.
Key note: These tests should identify key properties of the “real” element, to validate the FEA these tests do not have to look like the final load case and can be simplified.
