Computer Program Shock 2.0 Theory Manual

Abstract

SHOCK is a computer program designed to calculate the predicted shock pressures and impulses resulting from an explosion in a confined space in a manner consistent with procedures outlined in UFC 3-340-02 Structures to Resist the Effect of Accidental Explosions. As part of the official release of the ConfinedBlast 5.0 software (which includes the SHOCK program), minor updates to the methodology of the SHOCK program were implemented. This report details these updates, provides a history of the program, and documents the methodology of the calculation. The report also includes a validation study comparing the predictions of the SHOCK 2.0 software with experimental data and the results from the SHOCK 1.0 software(previously endorsed by the DDESB). This study indicates that SHOCK 2.0 provides improved accuracy compared to SHOCK 1.0. Although additional suggestions to improve the calculation methodology are possible (and discussed in the report), NAVFAC EXWC considers the software sufficiently accurate for the calculation of blast loads for use in the design of protective construction.
