Description
| - Cyclic uniaxial tensile tests of human aorta were performed with an aim to obtain data describing the Mullins effect. Significant stress softening of aortic tissue and residual strains were confirmed. It was hypothesized that the stress softening observed within reloading of previously loaded tissue may be described by an evolution of material parameters. The model based on changes in limiting fiber extensibility, primarily represented by a collagen, was proposed. The arterial wall was assumed to be hyperelastic transversely isotropic material with different response under primary loading and unloading. Every straining level in the cyclic test had its own value of fiber extensibility. Explicit form of the relation between evolving limiting extensibility and maximum previously sustained deformation was proposed. The predictions of the model described above were in good agreement with observations.
