A function of the specific energy of deformation, selected in the form of a number of exponents, is proposed. It describes well the stress-strain state of anisotropic human blood vessel at large deformations. The constants of the material included in the deformation energy function are determined by experiments for a monoaxial tensioning, along the main anisotropy axes. As an example, they were found for the human abdominal aorta, taken during an autopsy (male, age 29 years), by approximation of the experimental data on a computer by the method of least squares.
