user subroutines

Hi Abaqus experts

I am hoping that you can help me getting a element user subroutine writen in fortran f90 to work in Abaqus. I have made the simplest 8 noded brick element element that i can think of. I has a zero thickness and only has some simple definitions of the parameters ESTIFF,RHS,SVARS and PNEWDT. I have made a model with one single element of this user element where the upper part is displaced from the lower part which are fixed.

When I try to run the model I get the following message in the log file:

Help needed on VUINTER to define molecular interaction between two surfaces

Submitted by pphl on Wed, 04/27/2011 - 11:32

Hi,

Does anyone have any idea on using VUINTER to define adhesive contact between a hard body and a soft body (the potential between the two surfaces is molecular like van der waals or lennard-jones potential).

I wnat simulat rollong process. Mteral deformation is simulated by FEM and i want simujlate microstructure evolution by KMC method. Do any one have experience in this field (coupling FEM and KMC) ?

I want simulat micro strucure evolution in metal fromind, e.g. rolling. To capture grain growth or refinement, i use MC method and rolling process simulate by FEM method (ABAQUS). Do any one have experience in this field?

Can a beam act like a spring in relation to other spring?

Ask iMechanica

a simply supported beam (length= L) is subjected to an upward force= F at the middle , at the same time there is a spring above the top of the beam at the middle too and the spring is subjected to a downward force = - F .

the spring stiffness is k1, beam stiffness k2 (which equal to the force which produce 1mm deflection at the middle of the beam i.e = 48EI/L^3 ).

the beam can be steel beam UPN 80 , considering weak axis Y (19.4 cm4)
