I specified these values in my FEM Applications textbook. If you can find it, it will help you identify damage parameters for a Johnson-Cook model for steel. Here is the link to the book: link.springer.com/book/10.1007/978-3-319-67125-3
Hello Dr.Michael, I would like to know how to write code random particle in Matlab that can be imported into program Abaqus. Can you give me an example?😁😁🙏🏻
Hello @Rajasekaran, thanks for the feedback. I try to keep the volume of the music so low so they do not interfer with what I am saying. I feel having some background very low-volume music does help with the content but maybe not for you in this instance. However, thanks for taking time to comment and I will take the feedback on board.
Dear Dr.Okereke, i have a question. I would like to create a polycrystalline nickel model, like a cube with irregular geometry, but in Abaqus i can't choose the material like Ansys. Is there a solution about this? I'd prefer to create this model in Inconel 718. Thx for attention, best regards
Hi, yes you are right. In Abaqus you choose material models not the material itself. You have to find the underlying material model for Inconel and look for its equivalent material model in Abaqus. This is the way to go.
@@MichaelOkereke Ok perfect Dr.Okereke. I'll take this way. 1) i'll create my irregular geometry in Abaqus (i'll use UMAT's script) 2) Import this model in Ansys 3) Choosing the material for model (Inconel 718 in Composite Materials)

very interesting, thank you for sharing
My pleasure
Dr. Michel please make a SENB 3point bending following ASTM standard E1820 in 2D with XFEM.
Thanks for this. I am not working on this at the moment but I have noted it and if I can, I will try to make the video. thanks for your comment.
How to find displacement at failure for Johnson cook model and damage parameters or fracture energy for the same
This video should help you: ua-cam.com/video/gpSh2KLWnqk/v-deo.html
@@MichaelOkereke Sir what about damage parameters
I specified these values in my FEM Applications textbook. If you can find it, it will help you identify damage parameters for a Johnson-Cook model for steel. Here is the link to the book: link.springer.com/book/10.1007/978-3-319-67125-3
Hi sir can please make a video on steel .which is Directionally distributed in parallel Direction and perpendicular distribution in Abaqus
