Study Notes
Mechanical Properties of Materials
- A material's behavior when subjected to mechanical stresses is determined by its mechanical properties, including strength, toughness, ductility, hardness, and stiffness.
Metal Forming Processes
- Applied loads in metal forming processes cause plastic strains, which are non-reversible deformations that occur when a material is subjected to stress beyond its elastic limit.
Formability of Metals
- The ability to form metals increases with their ductility, which is the ability of a material to be stretched or drawn without breaking.
Stress-Strain Curve
- In the plastic region of the stress-strain curve, the material is primarily plastically deformed, meaning it undergoes permanent deformation without breaking.
Plastic Region Behavior
- A metal's behavior in the plastic region is expressed by its flow curve, which shows the relationship between stress and strain during plastic deformation, providing insights into the metal's plastic flow behavior.
