HEXDAM SOFTWARE

SUMMARY

HEXDAM represents the industrial version of the High Explosive Damage Assessment Model, now with the HEXDAM Man concept. Like its predecessors this software has been designed to allow the rapid evaluation of damage experienced by each structure within a facility as a result of a primary explosion, and any accompanying secondary explosions. Its primary application is siting analysis of explosive storage and manufacturing facilities. A number of technical papers have been published dealing with our work in this area. The code can also be used to evaluate terrorism and sabotage threats to an industrial or military facility. A demonstration of this software is available.

HEXDAM has the capability to model an unlimited number of structures, each with different dimensions and structural properties, including elevated structures, and also an unlimited number of personnel. The Parametric Analysis of Single Structure (PASS) capability allows the user to determine the influence of various important independent variables on pressure and damage experienced by an individual structure within a facility.

As with its predecessors, HEXDAM utilizes widely accepted dynamic pressure and overpressure curves to predict the pressure level at each structure/person location. Structure shielding, based on the three-doublet advanced shielding algorithm, and secondary explosion effects are calculated, and damage/injury levels are determined for each structure/person. HEXDAM produces output in the form of damage/injury tables, before-blast and after- blast displays, pressure and damage/injury contour plots, and damage/injury-versus-distance graphs, all in color. Advanced graphical features include three-dimensional graphics in the form of oblique projections, as well as two-dimensional horizontal and vertical cross sections for both pressure contour and damage/injury contour plots.

To ensure the software is usable by installation engineering, planning and safety offices, the hardware requirements for HEXDAM have been kept at a modest level. An IBM PC or compatible with a color monitor is sufficient to execute HEXDAM. Printing and/or plotting capabilities are included.

Recently, we entered into a working agreement with Trinity Consultants, leading to the development of HEXDAM 6.0 and 7.0 versions of our explosive safety software.
