Question: If a material exhibits plastic deformation, which of the following is true?

Options:

  1. It returns to its original shape after the load is removed
  2. It does not return to its original shape after the load is removed
  3. It behaves like a perfect elastic material
  4. It has a very high Young\'s modulus

Correct Answer: It does not return to its original shape after the load is removed

Solution: 

Plastic deformation means that the material does not return to its original shape after the load is removed.

Questions & Step-by-Step Solutions

If a material exhibits plastic deformation, which of the following is true?
Correct Answer: Material does not return to original shape
  • Step 1: Understand what plastic deformation means. It is when a material changes shape permanently.
  • Step 2: Recognize that when a material is deformed plastically, it does not go back to its original shape after the force is removed.
  • Step 3: Conclude that if a material exhibits plastic deformation, it will remain in its new shape.
  • Plastic Deformation – Plastic deformation refers to the permanent change in shape or size of a material when subjected to stress beyond its elastic limit.
