Convergence problem when including residual stresses

Convergence problem when including residual stresses

Convergence problem when including residual stresses

(OP)
Hi, I am modelling a simple plate structure and compressing it by applying an initial displacement to the master set tied to the left side of the plate using the equation constraint. When including the residual stresses by typing initial conditions, type stress, the error, 'time increment required is less than the minimum specified' arises. I am unsure how to solve this problem. I've attached an input file. Do help me!

RE: Convergence problem when including residual stresses

1. What is the value of the displacement you want to apply finally? There is no limit defined.
2. Why are you using Riks?

@Mustaine3. I am investigating the ultimate strength of the steel plate. I was advised to use Static Riks. I tried using static general, but there is no buckling. Sorry, I am a beginner at this.
