ME317g-MatScie_Lesson 4-5 (Mech'l Properties & Metal Structure)

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

• Plastic Region

• Strain

• Modulus of Elasticity

The amount of energy the material can absorb and still return to its original state.

• Strength

• Ductility

• Stiffness

• Resiliency

Measure of a material's ability to resist plastic deformation

• Ductility
