Abstract:

The overall objective of this project Phase I, II, and III is to develop, fabricate, and test a novel biofidelic rat surrogate for the validation of primary blast loading conditions for mild traumatic brain injury mTBI. The Phase I work summarized in this Final Report shows the CFDRCNJIT team was able to create a state of the art and first of its kind rat test device RTD to measure blast loadings in experimental inside a shock tube meant to mimic field blast conditions in a repeatable manner. A complementary virtual shock tube was also created to allow for predictive investigations of loading scenarios on the RTD to help guide future investigations and experiments and was partially validate for 3-D. This approach, a coupled experimental and computational investigation tool, will prove value to the Army to study blast loadings without live animals and also give a commonsingular test bed for future TBI research relating to rathuman blast loadings. The desire of the CFDRCNJIT team is to expand the RTD to include other test article options to create a suite of Blast Test Devices to assist in future blast investigations to the community at large. There remains no good way to correlate individual blast studies and investigations as each study uses different set-ups and devices with no common link. A suite of blast test devices could go a long way in linking these studies together and take a firm step towards creating defined blast standards for PPE and warfighter exposure.
