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. Fibers are supposed to be arranged in two families of anti-symmetric helices. Considered anisotropy corresponds to local orthotropy. 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 (0 - 4kPa) and four cycles under nonphysiological loading (0 - 21kPa). Each overloading cycle was performed with different value of axial weight. Overloading data were used in regression analysis to fit material model. Considered model did not fit experimental data so good. Especially predictions of axial force failed. It was hypothesized that due to nonphysiological values of loading pressure a
