A21    Identify the key mechanical properties that relate to elastic, plastic and a combination of elastic-plastic properties.

The key mechanical properties that relate to elastic, plastic and a combination of elastic-plastic properties include:

• Elastic or reverisble deformation

  • Proportional limit
  • Resilience
  • Modulus of elasticity

• Plastic or irreversible deformation

  • Percentage of elongation

• Combination of elasstic and plastic deformation

  • Toughness
  • Yield strength
