Hi, all.
We are modeling a cylindrical shell in Abaqus. The cylindrical shell was fabricated with PLA through the 3D printing technology. We did a tensile test and found that the global stiffness along the axial direction and circumferential direction is different. So, we tried to find a better way to model such varied stiffness in the Abaqus model. Any advice on how to define such material in elastic region would be appreciated.
