The purpose of this project was to identify a set of boundary conditions for the initiation of blunt traumatic aortic rupture (BTAR) in terms of thoracic accelerations and forces, to use in a later hypothesised creation of a fully dynamic finite element cardiovascular model. A secondary aim of the project was to look into the potential mechanism of the BTAR injury. The injury was researched by investigating past vehicle collisions, as such an injury is commonly seen in these situations. Occupant medical records and police collision records were used in order to simulate the specifics of the collisions, in terms of the occupant, vehicle interior and collision characteristics, with computer modelling software. The software allowed both validation of the simulation, by correlation of simulated injury with observed injury, as well as direct reading of the required thoracic forces and accelerations. The forces were found to range between 1427 - 2140 N and found to be predominantly unidirectional; and the accelerations were found to range between 2080 - 3476 m S- 2, again being largely unidirectional. No singular mechanism of BTAR was identified, however each collision did rule out at least one hypothesis. This confirms the multivariate hypothesis put forward, but also limits it to a small number of combinations rather than the whole spectrum. -
