The deformations of aortic walls in case of aortic aneurysm (dilation) and aortic wall dissection are studied. Numerical calculations of the load on the aortic walls at aneurysm and aortic wall dissection are carried out. It is shown that rupture of the inner layer of the vessel leads to an increase in the stress on the outer wall of the vessel. Increasing the thickness and length of the rupture increases the stresses on the outer wall of the vessel. The presence of an aneurysm of the vessel increases the stresses compared to a vessel without an aneurysm. Splitting of the inner wall of the vessel leads to an increase in the stresses on the wall — stresses decrease with increasing rupture width for a straight vessel and increase for a vessel with an aneurysm.
Keywords: aortic dissection, aortic aneurysm, mathematical modeling, hemodynamics, wall stress, biomechanics.
