Abstract and keywords

QUANTIFYING THE LOAD transferred to the clavicle when the shoulder is laterally impacted will assist automotive safety system designers interested in load paths during side impacts. This paper presents two non-invasive methodologies to estimate the force transferred to the clavicle by using multiple strain gage measurements taken in situ during a controlled shoulder impact.

The first methodology involved beam theory application to estimate compressive force from the strains measured in situ. The second methodology involved an additional set of bench-top experiments to reproduce the in situ strain distribution in vitro and thereby relate the measured strain to the applied force.
