2 cards from this section. Quick, good the night before a test.
Define the stress tensor.
Think about how forces are distributed at a point.
What does the diagonal component of the stress tensor represent?
Remember how normals relate to force directions.
What does the stress tensor primarily represent?
Focus on what governs internal stability.
True or False: The stress tensor has different meanings depending on the coordinate system used.
Consider how tensors behave under transformations.
You have a cuboid subjected to a uniform tensile stress of 100 N/m² along the x-axis. Calculate the components of the stress tensor, especially focusing on shear forces along the y-axis.
Consider the definitions of shear and normal stress.
A material shows positive σ₁₁ but negative τ₂₃. How would you interpret the states of stress?
Reflect on how shear and normal stresses interact.
