Fig. 3From: Numerical model of a valvuloplasty balloon: in vitro validation in a rapid-prototyped phantomStress-strain curves of valvuloplasty balloon material. In the left panel, data from failure tensile test on circumferential and longitudinal dumb-bell specimens, suggesting the assumption of isotropic behaviour up to 10 % of strain. In the right panel, data from cyclic tensile test on circumferential dumb-bell specimens show elastoplastic material behaviourBack to article page
