convergence problem - please help - urgent

[aero12345]

Hi every one,

I have to do damage modelling for a complex composite material, so just to check if it's going to work in ANSYS
I modelled a simple curved geometry of two curved materials (of similar properties or different), meshed with solid185 elements and seperated by interface elements.
But here I have problem with convergence just before reaching maximum normal stress of interface elements (INTER205). I tried with different element formulations also but still have this convergence problem. Please note that I am not looking for accuracy in this case and so the model is not meshed fine at the curves (does it affect the conrgence?).
Please help me find where I am going wrong, this is very important for my work.
I am attaching the input file for this problem for your understanding, please try this.

Thanks a lot for your inputs,
Vinston

Your Ex = 7.8886E-031 & niu = 7.8886E-031 for material number 1
I tried solving with Ex=7.886e5 & niu=.29 and ANSYS was able to solve it

Hi vtmike,

Thanks for trying out, but sorry that was just an error in creating the input file and I gave small load in that example, I have changed that again please see this updated file and let me know if it converges.

Thanks again,
vinston
