3 cards from this section. Quick, good the night before a test.
Define volumetric strain in your own words.
Think about how volume changes when materials are compressed or stretched.
What mathematical operation do you use to calculate the volume of a parallelepiped?
This involves three vectors.
What does volumetric strain measure?
Focus on what aspect of material deformation is captured by volumetric measurements.
True or False: Volumetric strain can vary based on the type of line elements chosen.
Consider how different strains behave under various conditions.
A cube of material measures 1m on each side before deformation. After applying pressure, its dimensions change to 0.95m, 0.95m, and 1.05m. Calculate the volumetric strain.
Use the volume calculation and relate your findings to the original volume.
Compare the volumetric strain of two materials subjected to the same deformation. One shows a significant change due to its properties, whereas the other shows minimal change. Discuss what factors influence this difference.
Consider how varying properties of materials can lead to different deformation responses.
