When this occurs and the stress is relieved, the material will no longer return to its original form, i.e., the deformation is permanent and nonrecoverable
Plastic Deformation
Ultimate stress
Strain
Young's modulus
It is the region where the material can be deformed and when released will return to its original configuration
Elastic Region

A tensile stress is to be applied along axis of cylindrical brass rod that has a diameter of 10mm. Determine the magnitude of the load required to produce a 2.5 x10^-3 mm change in diameter if the deformation is entirely elastic.
Note: the Poisson Ratio for the Brass v=0.34
