Figure 4From: Characterization of mechanical behavior of a porcine pulmonary artery strip using a randomized uniaxial stretch and stretch-rate protocolStretch history obtained by t h = 10, t h = 400, t h = 1000, and t h = 2000 (for 0–3000 sec). When t h is small, the stretch history is nearly the same as the instantaneous stretch, and as t h increases, stretch history reaches a plateau of λ = 1.5, the average stretch ratio of a random distribution in the range [1,2].Back to article page
