The pressure of 400 returns without problems and pressure set to 500 (next commfile) does not? The problem starts at t=7 or pressure 7/10*500 = 350, just below 400.
Can you check the stress at pressure 500 with a linear analysis? Is it above the yield stress (about 350 (M)Pa) of the specified material?

I tried it out with lower pressure (the measure of the units was MPa and i normaly work with Pa, so my pressure was 1,9e8 MPa and not 1,9e8 Pa .... ) and it finally works
But I have new questions
the increment of one step is 10 for 4 steps
so we got 40 increments
when I set the pressure to 4.e2 and the "ramp"-function to
0 - 0
t1 - 0.5
t2 - 1.0
t3 - 0.5
t4 - 0
I get additional increments at 20.25 and 20.75. Why?
And the displacement in result of the applying pressure "jumps" in the frame 19 to 20.
I uploaded the Mesh and comm file (the res file is too big), see next post please.
