Abstract
The aim of the work was a characteristic of anisotropic mechanical properties of a pig’s aorta. The isolated ascending, descending and thoracic aortas were taken. The longitudinal and transversal orientations of specimens taken were considered. Tissue strips were cut in the longitudinal orientation and in the transversal orientation as rings. Part of the rings was cut and indicated as the transversal strip samples, the second part in the form of rings was indicated as the transversal ring samples. The prepared samples were tested in an uniaxial tensile test. The values of the maximal force, the elongation, the ultimate tensile strength and strain at the UTS, Young’s moduli and energy of destruction were estimated. The influence of orientation of samples taking was estimated. The highest values of the maximal force and the UTS were determined for the transversal ring samples and the lowest for the longitudinal strip samples.
