Viscoelasticity and Dynamic Mechanical Analysis

Viscoelasticity is the property of a material that exhibits some combination of both elastic or spring-like and viscous or flow-like behavior.

Modeling the dynamic mechanical analysis of a single pulp fiber

Hi there,

 

I am trying to model the DMA test for single pulp fiber. In this research I can I assume whatever procedure or materials parameters I need, from an old PhD thesis I took some materials parameters for the cellulose, hemicellulose and lignin and by using the composite theories I calculated the stiffness matrices for each constituent I have and from there I calculated the stiffness matrix of the fiber, and of course calculated the longitudinal young’s modulus of the fiber at the room temperature.
