Predictions of aneurysm formation in distensible tubes: part b — application and comparison of alternative approaches

Significance of output:

This paper applies the methodologies outlined in Part A. The application of semi-analytic method is coupled with appropriate strain energy functions. It is necessary to use stress-strain data from at least two of the three uniaxial, equi-biaxial and pure shear methods of measuring (not just uniaxial data) to provide consistent predictions of critical pressure; indicating the onset of aneurysm.

Five distinct finite element types combined with seven strain-energy functions and various combinations of uniaxial, equi-biaxial and pure shear data are investigated. It is therefore demonstrated that engineering and medical applications has synergy through wave energy and abdominal aorta aneurysm investigations.
