    Strain energy function for arterial walls based on limiting fiber extensibility

  • Original language description

    An anisotropic strain energy density function based on limiting fiber extensibility assumption was suggested. The function was deduced directly from isotropic Gent model. A material was modeled as a composite reinforced with two families of helical fibers. The anisotropy of the strain energy function was incorporated via pseudo-invariants I4 and I6. Mathematical expression includes three material parameters. Suitability of the model for a description of arterial mechanical response was verified by regression analysis of experimental data. Computational model based on a cylindrical thick- walled tube with residual strains was used to estimate material parameters. Identified material model fits pressure-radius data of an aortic inflation test successfully. Further upgrades of the model are discussed.

    Funkce hustoty deformační energie pro cévní stěny založená na limitní průtažnosti vláken

  • Czech description

    Byl navržen anisotropní materiálový model pro cévní stěnu založený hyperelastickém popisu kompozitního materiálu s limitní průtažnsotí vláken. Model je primárně určen k modelování chování cévní stěny. Jeho funkčnost byla ověřena experimentálně.
