Question
Describe how a ductile fracture comes about?
Expert Solution

Step 1
Answer :
Ductile Material are those materials that go through substantial plastic deformation before fracture.
Examples
- Mild steel
- Aluminum
- Copper
- Plastics
Step 2
Ductile Fracture incurred when the intensity of stress exceeds the normal Tensile strength of the material. There are basically three steps involved in Ductile Fracture.
- Initiation of Voids
- Void coalescence ( crack formation)
- Crack propagation.
These steps are illustrated with schematic figure as shown (jpeg attached).
