hi all,

        i am very new to abaqus and i want to simualte sliding wear between a pin and a disc. i found from the literature that by using user subroutines we can calculate the wear. i am not getting how to use a user subroutine , can any one expain how to use user subroutines in the CAE. is there any simple example problems in understanding this user subroutine functions. thanks in advance. 

Prony series form :

gR(t)= 1- ( sigma(i=1to N)(gi(1-exp(t/τi))))

where,

gi= Shear relaxation modulus ratio

τi= Relaxation time

can anyone provide me the prony series upto 3 to 4 term for epoxy resin material....its urgent.

Dear All members

I would like to ask if any one can provide tutorials on NURBS subject related to coding in matlab ?for example matlab codes about  thin plate with hole or cantilever beam problem.

Thanks
