Predictions of aneurysm formation in distensible tubes: Part A — theoretical background to alternative approaches

Significance of output:

Most analyses of distensible tubes assume that stress strain data derived from tensile testing of sample material is sufficient to predict the occurrence of aneurysms. Furthermore, they assume that one can choose any strain energy function to perform the associated structural analysis. No published paper has been identified regarding the derivation of the governing equations.

This work is world leading since it provides governing equation derivations with two semi-analytic solution methods with satisfaction of the Valanis-Landel hypothesis and, Maxwell equal area rule with data selection criteria specified for realistic modelling and critical pressure predictions of a distensible tube.
