How to implement ductile damage localization in Abaqus?

24 April 2023 1 4K Report

Dear All,

I am totally new to countium mechanics and damage models.I need to implement a local damage model with von misses plasticity based on section 2.2.1. Damage Model in this article :https://www.frontiersin.org/articles/10.3389/fmats.2019.00181/full

However I am not sure how to implement a local damage model in Abaqus and where to start.Would be much more appreciated if anybody can help me!

Kind Regards,

Pardis
