Abstract

A finite element simulation of the operation of a nonbioprosthetic heart valve with leaflet geometry D.C. Webb, K. Kormi & R.A. Etheridge Centre for Advanced Research in Engineering, Leeds Metropolitan University, Calverley Street, ABSTRACT The Finite Element Method (FEM) is used in a preliminary study of modelling the operation of a nonbioprosthetic heart valve with a tri- leaflet geometry. The curvature of the leaflet and properties of the material are modelled as acurately as possible with our current information. The model is then subjected to loadings that simulate the pulsatile flow through the valve, hence mimicking the natural heart valve action. The model is developed in a paramteric form and its dimensions, shape, material properties, its method of attachment at its base, and also the shape and duration of the input pressure pulse, can be altered in the light of further and new information.
