Asme Section 8 Division 2 Limit Load Analysis

[Zack12]

I'm performing limit load analysis to verify my membran stress. I'm using abaqus software to perform limit load analysis.

My definition as fallows:

1) Material Property

Yield Strain
1.5*S

0

Load
1*5Fdesign.

So my issue is, My expectation is for abaqus to abort before the increment runs out It solves either 1000 increments or 2000 increments.
When I examine the stress figures, I think the analysis should aborted before increment finished because there is no connection between the boundary conditions and my analysis model.

Can anyone help about it. Thank you​

You're going to need to provide a whole lot more information if you want some assistance. Drawings, pictures, more thorough description of the model, loads, and boundary conditions, to start.
