Title: Determining rigid body motion from accelerometer data through the square-root of a negative semi-definite tensor, with applications in mild traumatic brain injury
Journal: Computer Methods in Applied Mechanics and Engineering
Algorithm predicts a rigid body’s motion using only four tri-axial accelerometers.
The body’s rotational motion is obtained without time integrating its acceleration.
Algorithm provides the complete kinematics of rigid body motion in the lab frame.
4 tri-axial accelerometers can be in any orientation and any non-coplanar position.
Algorithm will facilitate use of finite element method based brain injury criteria.
