Surfalex HF formability study - Workflow 3 - Fit yield functions

This MatFlow workflow is the third in a set of eight workflows developed during our formability study of the Surfalex HF (AA6016A) material. In this workflow, we fitted three anisotropic yield functions to yield stress data obtained from a large set of multiaxial crystal plasticity simulations. The fitted yield functions were: the Hill1948 yield criterion, the Barlat Yld91 (6-parameter) yield function, and the Barlat Yld2004-18p (18-parameter) yield function. DAMASK was used to perform these simulations.

This workflow can be downloaded and explored in a Jupyter notebook, as explained in the GitHub repository here.
