- In this video, we performed damage modeling of polymer on dog-bone sample. We covered strategy to do partition, damage constitutive model, and some technical details to make the simulation works (including convergence parameters).
Just a correction: Under tension of a cylindrical specimen the triaxiality is +0.333 not -0.333.
Thank you. You are the only one that explains the physical meaning of damage parameters required by ABAQUS, at least the only one I have found. Great work
Glad it was helpful!
Very Informative Ditho. I like the level of detail. One suggestion for those relatively new to FEA: it is always a good idea to check the mesh quality for errors and warnings, after meshing. There is a Verify Mesh icon (the one with the check mark on it) in the Mesh Module.
Thank you for your positive comment, Michael. Will include mesh vefirication in my next video. Thanks
Hello! The used dog bone specimen has standard dimensions or is it basically drawn for the simulation?
could you make a video combing Drucker Prager and ductile damange?
Thank you for this video hard to find good abaqus simulation out there
Thank you so much for this valuable tutorial. I was wondering if you could mention a scientific reference for using this damage model (for metals) on polymers?

@@FEADith Thanks a lot!
terbaik videonya.. membantu saya untuk buatkan simulasi spot welding. tq
Very attractive and useable
Thanks of teacher
Great work! Thank you !!!
Excelent video, which is rare when talking about Abaqus. Most people are only ready to correct othe people instead of helping. Thank you.
First of all, I would like to Thank you for describing DP model as well as Ductile damage in simplest way possible. I am using the same model and technique on a different material. However, I would like to discuss one or two things in detail. Do let me know, how can I reach out to you.
sir can you help me by keeping the shape memory alloy cantilever beam
hello! thanks for the tuto but i want a stress-strain data ? can u help me please !
Thank you for the video, it has lots of valuable information and has helped me understand some questions that i had.
I am still unsure how to determine the effective plastic strain in order to obtain displacement at failure.
Your example you give 100% but 100% relative to what?
Thank you, I hope you can help me ask this question and great job!
at the end, you can do trial and error to find this values that match your experimental curves, for examples...
100% is strain... so relative to what? it's a strain... relative to its original length of course LOL.
but here.. strain is 2 parts, elastic and plastic... 100% I mentioned is only the plastic part...
but again, get this value by calibrating (trial and error) to match your experimental curves
🤪🤪🤪🤪very good.hope make more video😋😋
Yes i will. Thanks
thanks for the video, I just have one question regarding material model: is it enough to have damage parameters just for only one triaxiality case? As you know, the stress state can vary at different positions.
when you model, nothing is enough... in the end it depends on what you want to model specifically.
if your case is tension dominated.. maybe one triaxiality data is enough... if your model is nonuniform, maybe putting 3 triaxiality cases is enough... but then strain rate is not uniform? then need triaxiality data for various strain rates? then the temperature is not uniform? then triaxiality data for various temperatures..? got the point? it really depends on things that matter for your simulations... so you really need to see what you want to see. LOL
Thank you so much for your informative and useful tutorial. That was exactly the kind of video I was looking for to learn how to do fracture simulation damage. I enjoyed your detailed explanations; plz keep up the good work!
Glad it was helpful!
thank you, hope more ABAQUS videos in the future with great explanation again! keep working!
Thanks, will do!
