Impact biomechanics

Research topics

The researches of the Impact Biomechanics team contribute to the injury risk prediction in the field of transports. The team develops both experimental approaches, from the biological tissues to whole body, and modeling approaches, both physical and numerical.
The activities can be divided in three domains:

  • Experimental biomechanics.
    This activity deals with the study of the mechanical behavior of human body parts, from biological tissues, organs to whole body. Liver, spleen, kidney, skin but also bone and costal cartilage are studied.

    • Ex vivo experiments are the main approaches to study the mechanical behavior in large strain, up to failure of the human parts and to study the effect of the strain rate on this mechanical behavior.

    • Non-destructive approaches are also carried out in collaboration with other expert laboratories in ultrasounds technics or medical imaging technics. The aim of these studies is to allow the in vivo measurement of the mechanical properties of biological tissues.

  • Finite element modelling for the study of human body response to impact

    The team is one of the world leaders on this activity (see GHBMC world project).
    The developed models are assessed by comparison with experiments from the literature and with experiments performed in the laboratory. Human body models help to better understand the mechanical response of the body to impact, and to better predict injury risks. This research activity focus on :

    • the child trunk (1.5, 3 and 6 years old)

    • the adult abdomen

    • scaling and positioning of the human body models

  • Anthropometric test devices (crash test dummies)

    The team works on the assessment and the improvement of the biofidelity of the trunk of crash test dummies. We developed an abdominal pressure transducer for the abdominal injury risk prediction. This transducer exists for the Q child dummies and for the THOR dummy. These developments are carried out in collaboration with several teams from Europe, Japan and USA.

The biomechanical knowledge acquired form experimental research activity is the basis for the development of tools for injury risk prediction as finite element models and crash tests dummies.
