Characterization and Modeling of Thoraco-Abdominal Response to Blast Waves. Volume 2. Blast Load Definition on a Torso Model
Abstract
The first step in developing the methodology for connecting the blast environment to bodily injury is to determine the distribution of mechanical loading on a test subject exposed to blast loading. The loading will be used to drive a structural analysis calculation that will predict local, internal stresses that can be correlated with damage. This report describes the use of a computer code to connect the gas dynamics of a blast field to the pressure distribution on the body and the validation of those calculations by data taken in the field. To make the validation process as pertinent as possible to the final application without being overly complex, a two-dimensional cross- sectional geometry was selected. A test fixture with the desired shape was constructed and instrumented. The data was reduced and compared with calculations made with JAYCOR's EITACC code. Extensive validation was carried out at occupational exposure levels and the agreement was quite good. A correlation was developed for extending incident load impulse to higher level waves.
