Session 15: Complex Modulus of Viscoelastic Polymers

Wednesday, July 8, 2020

Polymers are exceptionally complex materials—mechanical properties depend on chemistry, processing, and thermo-mechanical history. Instrumented indentation testing dramatically simplifies the mechanical characterization of polymers, because samples can be small and minimally prepared. On bulk materials, values for storage and loss modulus measured by indentation agree well with values measured by dynamic mechanical analysis (DMA).
