,
,Learning Outcomes
✓ Define and the concept of normal strain.
✓ Explain the physical meaning of Poisson’s ratio.
✓ Determine Poisson’s ratio experimentally from
measured strain data.
, Strain
Strain is the measure of deformation per unit length. It’s a
measure of how much a material stretches or shortens
relative to its original size.
