In order to study collapsible tube pnenomena sucn as flow in the tube, sell-excited oscillation of the tube and so on, it is important to elucidate the deformation characteristics of the collapsible tube as a model blood vessel when it is subjected to transmural pressure. Hence, we have studied a dynamic tube law that shows a dynamic deformation of the tube by numerical simulation. In this paper, we made a calculation about the deformation of a tube section by using a dynamic explicit finite element method. To evaluate the validity of our calculation, we calculated the static tube deformation and compared our data with conventional valid one. Also, we investigated the tube deformation when the tube is subjected to impulsive pressure. Their agreements with the conventional results are good.
