Abstract
A finite-element stress-analysis method for the left ventricular chamber is presented. The formulation uses an axisymmetric thick-shell element of the isoparametic type with three nodes to accommodate the meridional curved surface. The analysis also takes into account different fibre orientations across the myocardial wall. The method is used to determine the stress-distribution pattern of the human left ventricular chamber modelled as an axisymmetric shell for an isotropic medium and also for a layered wall.
