Modeling the dynamic mechanical analysis of a single pulp fiber

Submitted by Al Taib on

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.

 

I wrote a MATLAP code for the above procedure.

 

So far I have now problems, but now I do need to calculate the loss and storage modulus for the fiber at different temp, which I don’t know how to do it.

 

I did read and search a lot on line and in the library bout I could not find any book or article can help me to finish the research.

 

Any one can advice me?

 

Thanks
