Limiting Fiber Extensibility as Parameter for Damage in Venous Wall

Popis výsledku v původním jazyce

An inflation-extension test with human vena cava inferior was performed with the aim to fit a material model. The vein was modeled as a thick-walled tube loaded by internal pressure and axial force. The material was assumed to be an incompressible hyperelastic fiber reinforced continuum. Used strain energy density function was based on a concept of limiting strain extensibility. The pressurization was comprised by four pre-cycles under physiological venous loading and four cycles under nonphysiologicalloading. It was hypothesized that due to nonphysiological values of loading pressure and different values of axial weight the material was not preconditioned enough and any damage occurred inside the wall. Limiting fiber extensibility parameter Jm was assumed to be in relation to supposed damage. This approach turned out to be successful. Variable value of Jm can describe changes in the axial force - axial stretch response and satisfy pressure - radius depen
