Immersed in an ionic solution, a network of polyelectrolyte polymers imbibes the solution and swells, resulting in a polyelectrolyte gel. The swelling is reversible, and is regulated by ionic concentrations, mechanical forces, and electric potentials. This paper develops a field theory to couple large deformation and electrochemistry. A specific material model is described, including the effects of stretching the network, mixing the polymers with the solvent and ions, and polarizing the gel.

Zanaboni  Theorem  Is  Not  True

Hello,

I am planing to model a viscolestic material in ANSYS and condition is dynamic.

Could anyone please suggest what are the essential things (i mean datas) required for modeling a viscoelastic material?

For example, If I do the DMA test of viscoelastic materials i can have the modulus data at different frequencies. How to use those data in ANSYS to find out the stress-strain curve?

Thnaks for your kind help

Colleagues

Can I draw your attention to a Chair position and Lectureship in Bioengineering at the School of Engineering, Durham University. While the curent Chair position is occupied by an experimentalist, the postitions are open to candidates with interests in computational modelling and I would encourage anyone in that area to take a look.

Further details are available at the Durham jobs website https://jobs.dur.ac.uk/default.asp. Closing dates are 10/07/09 for the Chair and 31/07/09 for the Lectureship.
