Modeling of the Non-Auditory Response to Blast Overpressure
Abstract
The goal of this project is to develop mathematical models of the physical processes that cause blast injury so that the results of these tests using animals in simple blast environments can be safely translated to estimating hazard to man exposed to blast both in the free field and within enclosures. The present project builds upon an earlier work to develop models of the mechanics of the thorax and lung exposed to simple blast waves. The scope of interest has been expanded to include the lung exposed to simple blast waves. The scope of interest has been expanded to include the lung, and gastro- intestinal tract, the upper respiratory tracy, and the tympanic organs and to include a more extensive investigation of the magnitude and distribution of loading under a wider range of blast situations. The report covers the first year of the contract. Effort was concentrated in formulating a specific mathematical approach to each organ system, collecting and analyzing data from previous field tests, and developing models that can provide preliminary Damage Risk Criteria for the most susceptible organ system, the upper respiratory tract. Keywords: Lab animals; Lung injury; Neck injury; Blast overpressure; Pulmonary injury; Auditory; Hearing: & ear.
