Aneurysm growth is accompanied by formation of intraluminal thrombus. The onset of thrombus rupture via unstable void growth is studied in the present note. The experimentally calibrated constitutive model of thrombus developed by Wang et al. (2001) is enhanced with a failure description and used for analysis of cavitation. It is found that unstable cavity growth can start at hydrostatic tension of 0.18. MPa which lies within the physiological range of stresses in the arterial wall.
