Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a material under an unknown load. Given a stress matrix, derive the eigenvalues and discuss their significance in assessing material safety.

💡 Hint: Focus on understanding how these eigenvalues reflect the load application and material limits.

Challenge 2 Hard

Discuss how changes to one component of the stress tensor can affect the state of invariants and provide a practical example.

💡 Hint: Think about real-world applications where changes occur, like construction or vehicle manufacturing.
