Hello!
I am trying to define/assign initial stress to a coating I modeled on a substrate. I defined the coating using "skin" function. I have tried "predefine filed" in load section. But it only allows me to assign initial stress to the substrate (known as region), not the coating (skin). I appreciate your kind suggestions!
through this maybe you could predefine your initial conditions better and optimize with respect to your boundary surface conditions that you plan to apply to your structure.
Hey:)
I think there must be an option o merge both your surface and the coating. If there is no such option, then there must be the possibility to crop and combine the surface that is touching your coating.
Also, I see that you are good at FEM Simulation. Why don't you try to develop a code where the surface of your structure is also divided into a particular number of nodes.

Dear Shahida. Thank you for your answer. the surfaces defined by the "Skin" method in Abaqus are already merged to the substrate. The problem is "Skin" is a Shell element in nature. So far, I have had no success to assign internal stress to such elements. Shahida Anusha Siddiqui
Dear Mahdi Khadem
I think this might be helpful to you, it is the same thing that I think can work in your case as well: https://www.researchgate.net/post/How-to-introduce-intial-residual-stresses-on-Abaqus
