Název v původním jazyce

Simulation of residual stresses (strains) in arteries

Popis výsledku v původním jazyce

Residual stresses and strains contribute substan-tially to stress-strain states in arteries. They manifest them-selves by opening of the artery after having been cut longitudi-nally and can be quantified by means of the opening angle of a ring cut out ofthe artery and cut longitudinally afterwards. The magnitude of the opening angle changes with species, age of the individual, artery location, etc. Although the magnitude of these stresses appears slight, they can influence the stress (and strain) distribution in the arterial wall substantially by reducing the extreme values throughout the wall. Their surpri-singly high influence on the resulting stresses is given by the non-linear stress-strain characteristics of vascular wall. When applied to the blood pressure, the uniform stress and uniform strain hypotheses have been formulated to explain this pheno-menon. The usual way of their modeling is based on using a model with the geometry of the opened arterial ring; the resi-dual stresse
