Card 15 / 36: Which of the following statements best describes the difference between elastic and plastic deformation?
A)
Elastic deformation causes strain oscillations; plastic deformation does not.
B)
Elastic deformation occurs immediately upon application of a stress and reverses upon removal of the stress; plastic deformation is permanent.
C)
Elastic deformation occurs immediately upon application of a stress; plastic deformation occurs slowly.
D)
Plastic deformation occurs immediately upon application of a stress and reverses upon removal of the stress; elastic deformation is permanent.
E)
Elastic deformation results in dissipation of energy as heat; plastic deformation conserves energy.
Answer:
B) Elastic deformation occurs immediately upon application of a stress and reverses upon removal of the stress; plastic deformation is permanent.
