May inform simplified constitutive models of canine pulmonary arteries; leaves open translation to human physiology or clinical use.
Demonstrates an approximately linear stress-strain relationship in canine pulmonary arteries within physiological ranges and proposes a pseudostrain energy function.
Debes et al. (1995) studied this question. Biaxial tensile testing was evaluated on Stress-strain relationship. Biaxial tensile testing of excised canine pulmonary arteries demonstrated an approximately linear relationship between Kirchhoff stress and Lagrangian strain with very little hysteresis.
