The clavicle bone is the bone of shoulder joint which connects the upper limb with respect to the trunk. Each year there are thousands of clavicle fractures as a result of the three-point seat belt system in car crashes. Although a lot of testing is put into the safety of passengers during automobile crashes there is still some uncertainty concerning the realistic response of the anthropomorphic testing devices (ATDs) use to represent the passengers. This paper focuses specifically to create a more accurate representation of the human clavicle’s response during a collision. The geometry of the clavicle was created from converting CT/MRI-scans DICOM images of subjects into 3D-models. From theses scanned images it is possible to create a geometric model using the software like Catia or solidworks. This will be then imported to FEA analysis. In the case of car collision, the risk of clavicle fracture is more than any other bone in the body due to the three point seat belt system. So it is the need to create the precise and geometrically perfect clavicle model. Using the model created it was found that the peak stress occurs when the belt load is centrally located on the clavicle. The stress decreases slightly as the load is moved laterally (toward the shoulder) and decreases dramatically as the load is moved medially (toward the neck). The process and model developed in this study could help in the creation of more accurate bone representations in ATDs for crash testing purposes and also helpful to develop customized anatomical implants.
