Finite-strain Visco-elastic Visco-plastic model identification of PA12 material printed along different directions

The data provide the identification of PA12 bulk material for a finite-strain visco-elastic-visco-plastic (VE-VP) model printed along two directions.

Tests were conducted in L. Cobian, M. Rueda-Ruiz, J.P. Fernandez-Blazquez, V. Martinez, F. Galvez, F. Karayagiz, T. Lück, J.

The model

• Is implemented as a cross platform UMAT subroutine that is openly available on https://gitlab.uliege.be/moammm/moammmpublic/-/tree/master/code/MaterialModels/FiniteStrain/Finite_VEVP (Licensed under the Creative Commons Attribution 4.0 International (CC BY 4.0) (https://creativecommons.org/licenses/by/4.0).) and referenced on the project web-site https://www.moammm.eu/index.php/developed-code/.
• The model is also implemented at the cm3 laboratory, who provides efficient algorithms for homogenisation implemented in a parallel setting in the open source finite element code base on Gmsh. In order to have access to the sources follows https://www.moammm.eu/index.php/developed-code/.
