  • Human tolerance to blunt impact

    Dear Biomech-L members,

    Dynamic fracture forces of most body parts, as related to motor vehicle, is
    well documented in the literature (e.g. SAE reports). For instance, the
    force necessary to fracture the femur is generally determined from
    biomechanical testing where impact is delivered longitudinally through a
    flexed knee.

    *** Here is now my request:

    As opposed to the experiments carried out in the automobile industry, where
    long bones are loaded longitudinally, I am interested in knowing how much
    force (or energy) is needed to fracture the long bones of the limbs as a
    result of blunt impact delivered in a transversal manner (perpendicular to
    the bone shaft). Malicious kicks to the tibia and bat blows on the forearm
    during violent assaults are two examples among others where such forces may
    be applied.

    Any information would be much appreciated and, of course, I will post a
    summary of the responses.
