Název v původním jazyce

A comparison between exponential and limiting fiber extensibility pseudo-elastic model for the Mullins effect in arterial tissue

Popis výsledku v původním jazyce

This study compares the capability of two different mathematical forms of the so-called softening variable to describe strain-induced stress softening observed within cyclic uniaxial tension of the human thoracic aorta. Specifically the softening variable, which serves as the stress reduction factor, was considered to be tangent hyperbolic-based and error function-based. The mechanical response of the aorta was assumed to be pseudo-hyperelastic, incompressible and anisotropic. The strain energy densityfunction was employed in classical exponential form and in not well-known limiting fiber extensibility model. This study revealed that both the limiting fiber extensibility and exponential models of the strain energy describe mechanical response of the material with similar results.
