Discussing the Linear Viscoelastic Region and Selecting a Strain Value

In this Tech Tip, we discuss how to identify the end of the linear viscoelastic region so quality data can be generated within the linear region. When conducting tests on a rheometer or dynamic mechanical analyzer, data must be measured in the linear viscoelastic region for an accurate reading. Viscoelastic properties such as storage modulus, loss modulus, and tan delta become strain dependent at the end of the linear region. Learn how to easily determine the linear viscoelastic region on a rheometer or DMA.
