High Explosive Damage Assessment Model Advanced Industrial Version (HEXDAM-D+)

Abstract

HEXDAM-D+ represents the fourth industrial version of the High Explosive Damage Assessment Model. 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. The code can also be used to evaluate terrorism and sabotage threats to an industrial or military facility. The program has the capability to model an unlimited number of structures, and each with different dimensions and structural properties. The Parametric Analysis of Single Structures (PASS) capability allows the user to determine the influence of various important independent variables on damage to an individual structure within a facility. As with its predecessors, HEXDAM-D+ utilizes widely accepted dynamic pressure and overpressure curves to predict the pressure level at each structure location. Structure shielding based on an advanced shielding algorithm, and secondary explosion effects are calculated and damage levels are determined for each structure. HEXDAM-D+ produces output in the form of damage tables, before-damage and after-damage displays, pressure and damage contour plots, and damage-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 overpressure, dynamic pressure, and damage contour plots. To ensure the software is usable by installation engineering, planning, and safety offices, the hardware requirements for HEXDAM-D+ have been kept at a modest level. An IBM PC-XT/AT/386/486, or compatible, with a color monitor, a dot matrix printer, and a color plotter (for hardcopy of screen graphics) are sufficient to execute HEXDAM-D+.
