Key result
Biaxial creep tests of porcine pericardium demonstrated deformation in the circumferential and radial directions of 3303 × 10−6 and 5192.9 × 10−6, respectively, after 30 minutes.
Why the study?
Predicting leaflet failure and fatigue is essential for designing novel heart valve bioprostheses, but standard uniaxial and biaxial mechanical tests do not fully capture time-dependent viscoelastic behavior.
Biaxial tensile testing of porcine pericardium yields critical viscoelastic parameters for numerical simulations of long-term aortic valve bioprosthesis performance.

May improve bioprosthetic aortic valve durability predictions; extends viscoelastic parameters for long-term numerical simulations.
Matjeka et al. (2026) studied Aortic valve bioprosthesis design. Biaxial tensile creep and stress relaxation tests was evaluated on Viscoelastic response (creep and stress relaxation behavior). Biaxial creep tests of porcine pericardium demonstrated deformation in the circumferential and radial directions of 3303 × 10−6 and 5192.9 × 10−6, respectively, after 30 minutes.
