How does strain rate influence the mechanical deformation of silicone rubber impression materials, and how does it influence impression technique in terms of how the impression is removed.

The question has several questions inside it.

Q: Viscoelasticity is an important consideration of silicone impression materials. How does strain rate
influence the mechanical
deformation of silicone rubber impression materials, and how does it influence impression technique
in terms of how the impression is removed. Appropriate theoretical model diagrams and stress-strain
relationships should also be used to illustrate your answer.
