Sketch a labelled graph of stress against strain for a ductile material  and it main features.

Explanation

• OA – stress is proportional to strain and the material regains its length
• AB – stress is not proportional to strain but the material regains its length
• Beyond B the material becomes permanently stretched
• CD the material undergoes plastic deformation
