Abstract

In this paper, a methodology which was devised to develop and validate a simple, easy to use biomechanical surrogate of the thorax made up of corrugated sheets that can minimize the use of experiments with anesthetized animals, cadavers and expensive Finite Element Models for evaluation
of blunt thoracic trauma, is presented. Though the methodology presented in this paper was aimed at developing a surrogate of the thorax which emulates 3-RCS (a widely used high fidelity thorax model developed by Wayne State University), to prove the feasibility of the proposed methodology a pilot study was carried out in which, a target made up of corrugated sheets was correlated with the thorax of the Hybrid III ATD. For the pilot study, a series of computer aided engineering (virtual testing) analyses were carried out with the thorax of the Hybrid III 50th percentile rigid male dummy, which was impacted with a 27.3 gram, 40 mm projectile with foam nose and PVC base, at 50–100 m/s (with an increment of 5 m/s) and force–time responses were measured. By varying the design parameters of
the target, numerical simulation iterations were carried out to achieve the correlation with the thorax of Hybrid III dummy.
