Visco-elastic behaviour of materials which is time dependent is common in______________?
Correct answer: B. Non-crystalline organic polymer
- A. Plastics
- B. Non-crystalline organic polymer
- C. Non-crystalline solids
- D. Crystalline solid
Explanation
Time-dependent viscoelasticity is especially characteristic of non-crystalline organic polymers because their long molecular chains slowly rearrange under load. Crystalline materials generally show less pronounced polymer-like viscoelastic behaviour.
