Dear Dr. Jorgen


I am working on sliding behavior of rubber block on Road surface.

I would like to use Huemer model to represent surface interaction
in which the coefficient of friction is function of sliding velocity, temperature and contact pressure.

I would like to learn incorporate this Huemer model in abaqus CAE using subroutine

I am waiting for your reply

Hi I seem to still be having problems with my results. When I plot my Stress/Time curve to get a pulse the graphs all seem to be wrong.My curve instead of a neat pulse is a series of undulating peaks and valleys.

Hello all,
I am doing finite element analysis on Cardiovascular stent. To model an artery i m using Mooney Rivlin equation but the problem is i dont have its coefficients. Can any one help me out where can i get this or if you suggest some other equation do let me know. By the way i am using ABAQUS software. Thank you
