Challenge Problems

Push your limits with challenges.

Question 1

If a material's behavior deviates significantly from linearity under certain load conditions, how would this affect the application of Taylor's expansion? Provide a detailed argument.

💡 Hint: Consider the implications of large deformations and how they might impact dependency relations.

Question 2

How would you apply Taylor's expansion in a scenario where you have a composite material and different properties for its constituents? Describe your approach.

💡 Hint: Think about how the properties interact and consolidate results using rules for composites.
