Our blast group has extensive experience calculating blast, fragment, and thermal loads from internal and external detonations and deflagrations. This experience includes many research projects for the U.S. government where our engineers have planned and overseen large blast and fragment testing programs and analyzed test results to develop improved methodologies for calculating blast and fragment loads. Our blast test experience includes shock and gas pressure loads in the explosion room from internal detonations, blast propagation within buildings through failing walls and doors, debris throw from structural components failed by blast, and external “leakage” blast loads from the shock wave of an internal detonation that propagates out through openings in buildings. Our group has experience calculating blast and fragment loads from project-specific methods we have developed and using available fast-running codes from the U.S. government to calculate blast loads including ConWep, BlastX, and the SHOCK and FRANG codes, as well as weapon fragment databases. We also have experience calculating injuries to building occupants from blast loads and failing structural components of buildings. This includes development of the BICADS methodology that is used by the DoD to estimate injuries for blast loaded buildings.
