Challenge Problems
Push your limits with advanced challenges
Given a strain tensor with J1 = 5, J2 = 3, and J3 = 1, discuss the implications of these invariants on material behavior during deformation.
💡 Hint: Consider how each invariant affects material performance.
If the strain tensor is diagonal with eigenvalues 2, 1, and 0, calculate J1, J2, and J3. Assess what this means for the material.
💡 Hint: Focus on using the definitions of trace and determinant.
