Understanding Strain-Rate Sensitivity In Polymers

摘要

A fundamental principle of viscoelastic behavior is the equivalence of time and temperature in determining the behavior of a material. Since all polymers are viscoelastic in nature, this principle applies to the mechanical properties of all things plastic. Unfortunately, these principles are typically addressed only in textbooks that provide a very rigorous mathematical treatment of the subject. The practical significance tends to get lost in the math; consequently, engineers who design plastic parts and specify raw materials remain unaware of this very important principle.
