Original Abstract

In the paper stress distributions calculated on the basis of different finite element (FE) models of AAAs are compared to assess the acceptable simplifications. The simple quasi-linear constitutive model without residual stresses and without taking unloaded shape into account can offer acceptable results for simple geometrical shapes but is not applicable for credible evaluation of stresses in patient specific models of AAAs.
