Effect of Strain Rate on Tensile Properties of Tissues in Tail Flukes of Dolphin

摘要

The mechanical properties of the tissues relates with the propulsive performance of the tail fins of dolphins. In this study, the tensile properties of the main two tissues in the tail flukes of a dolphin, that is, the ligamentous layer and dense connective tissue are investigated. As a result, the tissues all showed the effect of the strain rate which weakened gradually as the strain increased. The moduli obtained at different strain rates tend to converge.
