Computational modelling of stress and strain states in aorta

Original language description

The presented computational model of stress and strain states in the aortic wall respects blood pressure, axial prestretch, residual stress and a multilayer structure of the wall. It shows a pronounced influence of the additional load factors decreasongthe maximum circumferential stress and the extreme stress ratio substantially. This can be generalized for residual stress state in any multilayer cylindrical vessel. Thus applications in practical technical computations are enabled (plastic tubes). There exist physiological blood pressure values, at which either the stress or the strain state in each layer of the wall is nearly homogeneous. A sensitivity analysis of the influence of surrounding tissues on the stress and strain state of the aorta was carried out. The results depend a great deal on boundary conditions used in the model and on elasticity moduli of surrounding tissues.
