Challenge Problems
Push your limits with advanced challenges
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.
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.
