- •
The printing direction effect is studied and modeled for photopolymers.
- •
A transversely isotropic hyperelastic-viscoplastic model is developed.
- •
The plastic model considers material anisotropy and pressure-sensitivity.
- •
A failure criterion is proposed for glassy polymers with strain softening.
