Background: Many traffic accidents give rise to long term
effects on the people involved even in cases where the velocity is moderate.
Whiplash is the result of very large accelerations of the head leading to
many side effects in different parts of the upper body. Not ll of these effects
have found a physical interpretation. In order to understand the physics
involved a new theory has been proposed by a group of doctors. The theory
needs verification and part of this may be done by defining a mathematical
model and use numerical experiments on the basis of the new theory. Neuro
anathomy of the Cerebral Spinal Fluid (CSF) leads to the following hypothesis:
When the neck in a whiplash situation is prolonged the shape of the spinal
channel is changed accordingly. There is in the cranium and spinal
chord nothing but fluid and tissue, this means that the volume of the CSF
cannot change unless cavitation takes place. This cavitation can only happen
in extreme cases with sudden pressure drop. Will such a situation be possible
in a traffic accident?
Aim: Build a mathematical model based on a simplification
of the topology found in a human body. Design a FEM model that makes
it possible to simulate the scenario of a traffic accident. Carry out simulations
on the FEM model for verification of the hypothesis proposed by the doctors.
The simulations should use realistic values of the sizes and properties
of the volumes and fluids. This information is supplied by the team of doctors
Prerequisites: Knowledge of fluid mechanics, partial differential
equations, Finite Elements, as well as Fortran, C, or C++ for the modelling
and Matlab for the visualization.
