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

description: 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.
