Hello Everyone,
I have the effective properties of a material (E1, E2.. v12, etc) as a function of the strain (epsilon11, epsilon22, epsilon12) as shown in the figure.
I want to apply these properties as Engg Constants to a cylindrical model made of solid elements (as shown).
I would love to get some information on:
1. How does Abaqus work when the strain that the model experiences is greater than the combination of strains I have mentioned in the Engg Constants?
2. How do I apply anisotropic properties orientation to only the middle layer of a solid cylindrical model made of 3 layers?
Thank you for your time!
What about the outer & inner layers? they will have isotropic properties?
Hello Mohammed, yes you are right : The inner and outer layers will have only Isotropic properties. Do you have any idea how I can assign the anisotropic properties such that the young's modulus changes based on the deformation during the analysis?
Dear Jonah,
If you want to have an updated elastic modulus for each increment, you need to write a UMAT subroutine. Another possibility is to use filed variables and write a USDFLD subroutine to assign elastic modulus during the running time.
