Elastic-Plastic Analysis - Determine the maximum load for a burst test

Elastic-Plastic Analysis - Determine the maximum load for a burst test

Elastic-Plastic Analysis - Determine the maximum load for a burst test

(OP)
Hello all,

I'm using ANSYS 18.2 Workbench Enterprise.

I am running an elastic-plastic analysis in accordance with ASME VIII Div 2 Part 5 where I wish to determine the maximum pressure load at the point I am predicting the design to gross plastically collapse.

Is there an easier and more efficient way of being able to set a range of input pressures then running for all those values until the solver does not converge?

Currently I'm running as-standard by inputting the pressure, doing a step load with program-determined sub steps, awaiting the result at which point the model doesn't solve then making note of that pressure in which the model doesn't solve - THIS TAKES FOREVER!

Is there a better way? Is there an in-built iterative way?

Kind regards,

David.
