Hello, 



i am using Abaqus/Standard to simulate the contact of a ball with a flat. Up to this point the simulation is no problem and gives good results compared to the herzian theory. But within my bachelor thesis i have to add a coat (with layers) to the flat (Thickness: 0.004 mm) and analyse the influence of the coat material to the stresses. My idea is to create a skin on the plate and a shell composite section. Then i assign the skin to this section. In the field output i defined the section points to get the stresses over the thickness of the shell. 

I am doing analysis of crack in pipeline as part of my masters degree. So kindly suggest me what are the procedures i have to proceed for the same.

 Thanks and Regards,

Mahesh 

Dear all, 

   I am using ABAQUS  to perform the nonlinear buckling study of composites right now,  I am also trying to use Virtual Crack Closure Technique(VCCT) to study the strain energy release rate. However,here I have some questions regarding to obtain the nodal force and nodal displacement.

1. Could anyone give me some ideas how to obtain nodal force in Abaqus?

Hi,

Is there anyone aware of the reason why there is a surge in hardness value during the initial stages of penetration in nanoindentation curve. In a plot of hardness vs displacement into surface, I record a high value during the initial stages of the run. I am little confused about the reason.

Thanks,
