About THOMO : Project overview

Presently, the vehicle safety devices used as prevention tools shall be improved, since they were developed in an outdated context, for a mean person and a limited area of application.

Numerical human body models could be used instead of anthropomorphic dummies to assess injury risks in different accident scenarii, to adapt accordingly vehicles and then regulations.

The present project proposes to give to passive safety players a tool capable of assessing real safety. It aims to create and maintain biofidelic finite element models of the human thorax including upper extremities based on the research, development, and validation of the models for the 5th, 50th, and 95th percentile of each gender.
 

It is based on the following steps:

• development and maintenance of a biomechanical database of tests at the segment (thorax) and organ (heart, lungs, aorta) levels with the necessity to define the mechanical validation criteria of the model and to improve the knowledge of the mechanical behaviour of the organs and of the mechanical and geometrical properties of the rib cage;
• development of numerical models from the CAD data with the necessity to personalize these data, to define a model architecture allowing its validation at the mechanical and injury levels and to quantify the numerical and mechanical consequences at the fracture level;
• mechanical and injury validation of the thorax and of the upper extremities with tests coming from the literature or performed during the project.
