Mechanical Response of the Human Aorta to the Delamination at Different Loading Velocities
Original language description
Our study deals with the delamination strength of the human aorta. Rectangular strips of the aorta were obtained from three different locations - ascending thoracic aorta, descending thoracic aorta, and abdominal aorta. Peeling experiments were designed to take into account possible effects of arterial anisotropy and a rate-dependent mechanical response. The peeling was carried out at four different loading rates: 0.1, 1, 10, and 50 mms-1. The experiments carried out with samples received from the ascending thoracic aorta and from the abdominal aorta did not show significant effect of the velocity on the delamination strength. On the other hand, the results suggest that in the thoracic region descending aorta delaminates at significantly higher force when teared at 50 mms-1 in comparison with the delamination conducted at speed of 0.1 mms-1. This result was found for both circumferential and longitudinal orientation of samples.
