Abstract

Although the application of injury biomechanics principles has been distinctly successful in reducing fatalities and injuries in fields as diverse as automobile biomechanics and the military biomechanics of blast, and ballistics, there are substantial challenges in generating revolutionary advances in our understanding of injury etiology and risk leading to improvements in design and injury countermeasures. Each of these challenges present promising research opportunities for future injury biomechanics. This talk will explore a small sample of interesting and important problems in current research and potential future research directions.

For example, every failure that concern of modern injury biomechanics is actually some form of post failure behavior. For example, initiation of bony fracture is very local (cellular level) while our injury risk functions are typically macroscopic systems or systems of systems. This implies breakdown of typical initial assumptions in material response and failure behavior, with implications for theoretical, experimental and computational analyses and risk analyses. Details of this post failure behavior are often important, especially in computational models, perhaps with nontrivial effect on our analytical conclusions for failure evolution and extent.

Another principle area of opportunity is soft tissue biomechanics, also in each the theoretical, experimental and computational aspects. On the physical side, the complexities of complex viscoelasticity, lack of homogeneity and heterogeneity, and other basic material complexities, provides problems and opportunities at various strain rates, while the fundamental difficulty of modeling response in soft, nearly incompressible tissues suggests the need for directions beyond those widely used in current body modeling.

This survey, as a matter of course, will be limited and particular to the speaker’s perspectives and peccadillos.
