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.

 

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

Dear Al Taib

 Here you can find the loss and storage modulus for the spruce specimen at different temp:

Obataya, E., M. Norimoto, et al. (1998). "The effects of adsorbed water on dynamic mechanical properties of wood." Polymer 39(14): 3059-3064.

 Kind Regards,

Ahmad

Dear Ahmed

Where can I find this article?

and if u have it would u plz send it to me
