Error 4760 - no convergence in nonlinear quasistatic calculation

Hello,

 

I have a problem with the convergence of a nonlinear quasistatic calculation of a solid model.

 

Attached you can find the .hm file of it.

 

I want to consider nonlinear material behaviour by using a TABLES1 Collector starting at the yield strength for a MAT1 Material

 

The longitudinal beam has one groove in the middle where it should start to buckle.

 

So one front surface is firmly fixed and the second side is fixed by translation. The displacement is placed at the second front surface with an SPCD and the deformation is 30 mm.

 

I wanted to analyse the difference between large and small displacement but unfortunately both calculations end with a convergence error.

 

For this I increased the number of increments but the result is still the same.

 

Can you tell me, where the problem is?
