Hello fellow researchers,

I am almost completing my first year in research study and am finding it difficult running my structural simulation in ABAQUS once I have included non-linear geometric effects. I didn't have problem with the simple heat transfer analysis. I have also converted (--) to the true stress-logarithmic strain curves at elevated temperatures using the empirical model given in EC3, yet no good outcome. Can anyone suggest to me how I could go about it?

Comments will be gratefully appreciated.
