A growth model of small artery for the vibration induced Raynaud syndrome situation.

This paper presents a method of modeling cell growth phenomenon of the arterial wall exposed to vibration. The arteries constantly adapt their morphology to counter the effects of internal disorders or external stresses. It is assumed that exposure to vibration can induce this phenomenon directly or indirectly. The approach is inspired by the mechano-biological models used to predict long-term effects of hypertension. An artery section has been modeled in 2D and an external pressure was applied to both sides with a static component and a dynamic component. Calculations show that the model used predicts a localized growth in the free lobe which is mainly due the static component of the pressure applied. These results are a step in our approach to be extended to the modeling of animal experiments whose observations available in the literature allow us to tune the parameters of the model or to adapt this model.
