An Anisotropic pseudo-elastic model for the Mullins effect in arterial tissue

Popis výsledku v původním jazyce

This paper is focused on developing the theory which describes the Mullins effect in human arterial tissue. Cyclic uni-axial tensile tests were performed to obtain data characterizing the Mullins effect in arterial tissue. The arterial wall is consideredas hyperelastic, locally orthotropic, incompressible material. A strain energy function is adopted in the limiting fiber extensibility form. Description of primary material response, followed by material stress softening in the repeated cycles, is basedon pseudo-elastic constitutive model proposed by Dorfmann and Ogden. This theory is developed using anisotropic form of the softening variable. The primary loading curve and the fourth unloading curve of each set of cycles are chosen for regression analysis. The model with thus estimated parameters successfully fits experimental data and is suitable for application in biomedicine.
