2 cards from this section. Quick, good the night before a test.
What is the strain tensor?
Think about how materials change shape.
List the three components of the displacement vector in cylindrical coordinates.
These correspond to radial, circumferential, and axial movements.
What is the primary function of the strain tensor?
Think about what happens to materials under load.
True or false: An isotropic material has different properties in different directions.
Focus on the 'iso' prefix.
Consider a cylindrical rod subjected to tensile loading. Derive its strain matrix and explain each term's physical significance.
Focus on the directions of applied loads.
Analyze a hollow metal cylinder under internal pressure and derive the equations for ε_rr and ε_θθ. Discuss the implications of these strains.
Consider the relationship between pressure and tension.
