Abstract : An improved version of a previously reported long bone injury criterion has been developed. This new criterion was based on fitting the Ramberg-Osgood equation, through optimization techniques, to existing stress-strain-strain rate curves for compact bone and using this equation to solve for the strain at a time step given the current stress and the strain from the previous time. Refinements have also been made to the geometric modeling of the bones where adequate data existed. When coupled with the Articulated Total Body (ATB) model and relations between ultimate stress and strain rate, this criterion has provided an effective means of judging long bone injury potential.
