Altair's French office 'Altair Development France' has helped to develop a detailed finite element model of an entire human body. Basicaly a human body was frozen in a car driving position, cut into thin slices from which the geometry was exctracted to create the computational model called HUMOS, version 2 by now.

HUMOS - human model for safety, used to assess the injuries that can be sustained in accident scenarios, a project funded by the European Commission.

First, human bodies were used in safety research in order to create the crash test dummies. Then computational models of the crash test dummies were created. Nowadays, the real crash test dummies are used only rarely.

As the computer technology progressed, the models of humans were created at last. HUMOS has all the internal organs, ligaments, 206 bones, everything that a complete human body has.

The animation shows HUMOS in front impact sled test to simulate the injuries on occupant travelling at 50 km/h (31 mph). It's cut so the internal organs can be seen.

With the designed sensores, the head acceleration, among other things, can be measured and the head injury criteria (HIC) can be computed to establish whether it exceeds the biomechanical limit.

In the case of the animation the HIC reached a value of around 300 while the limit is 1000, HUMOS survived, this time.

Lubo: looks unpleasant...
why is it that most of the times it's the right leg, arm and part of the torso that are most endangered, is it because of the way the seatbelt is designed to tied us?
