Figure 7From: Characterization of mechanical behavior of a porcine pulmonary artery strip using a randomized uniaxial stretch and stretch-rate protocol Relationship between short-term stretch history and stretch rate. (a) When the stretch rate is positive, the stretch history for t h = 10 sec is less than the current stretch ratio. (b) When the stretch rate is negative, the stretch history for t h = 10 sec is greater than the current stretch ratio.Back to article page
