Viscoelastic behaviour is observed in _______________________ materials?
Correct answer: A. Non-crystalline organic polymeric
- A. Non-crystalline organic polymeric
- B. Ceramic
- C. All crystalline
- D. All amorphous
Explanation
Viscoelasticity is especially characteristic of non-crystalline organic polymers, which show both elastic recovery and time-dependent viscous deformation. Ceramics and fully crystalline materials are generally much less viscoelastic under ordinary conditions.
