4 cards from this section. Quick, good the night before a test.
What is local volumetric strain?
It relates to how much volume changes during deformation.
Explain what a displacement gradient is.
Think of it as the rate at which points in a material move.
What does local volumetric strain measure?
Focus on how deformation impacts volume.
True or False: The volumetric strain is independent of the choice of line elements.
Recall how strain is defined.
A cube with a side of 1m is deformed such that its new dimensions are 1.1m, 1.0m, and 1.05m. Calculate the volumetric strain.
Calculate the new volume first and then apply the volumetric strain formula.
Discuss how volumetric strain can influence the material properties of concrete under compression.
Think about how pressure contributes to structural failure.
