Residual stresses in a fiber model?

[tperea]

Has anybody included initial residual stress/strain in a fiber model?

[silvia]

sure, it depends on the material.
concrete02 is a good example of it.

This is for a steel cross-section modeled with fibers. Each fiber may have a different value of initial residual stress or strain due to the fabrication process. I'd appreciate any idea.

Hi,

Have you known how to impose residual stress or strain to a fiber section for the case when each fiber of a section have different residual stress or strain? It would be really appreciated if you can give some ideas about this problem. Thank you

you can add the fibers individually to a fiber section, so each one could have its own initial values.
