1: Ductile Fracture

In a tensile test (where the load is in tension) a material can either: 

Behave in a highly ductile manner:

 

 

  • Large plastic deformation
  • Polymers and very soft metals deform this way

 

 

 

 

Behave in a moderately ductile manner:

 

 

  • Moderate plastic deformation
  • Most metals deform this way
