Tensile test of the aortic vessel specimens
(a) Instron 8744 servohydraulic test systems (Instron, Grove City, US)
(b) Prepared aortic vessel specimen with the required shape
(c) Specimen longitudinally loaded onto the test system
(d) Measure of the initial specimen lengths using vernier caliper
(e) Specimen stretched on the system with a certain load range and pulling speed
(f) Data of tensile strength that can indicate the mechanical strength of the specimen was collected at the time when the specimen was stretched to fracture
