BREEZE ExDAM® (Explosion Damage & Injury Assessment Model) is a unique, efficient 3D explosion consequence modeling suite that allows users to predict injury and damage resulting from the detonation of high explosive and vapor cloud explosions. BREEZE ExDAM contains the High Explosive Damage Assessment Model (HExDAM) and Vapor Cloud Explosion Damage Assessment Model (VExDAM). These numerical models provide a fast and accurate means to calculate structure damage and personnel injury due to over-pressure (OP), dynamic pressure (DP), and impulse (IP) distributions.
Take a look at the companion product, BREEZE VASDIP, which is designed to compute vulnerability parameters of structures and human body components resulting from explosion impacts for use in BREEZE ExDAM HExDAM and VExDAM modules.

Failure to identify and mitigate explosion hazards is a persistent cause of industrial accidents, impacting sites ranging from fertilizer storage facilities to refineries. While some explosion consequence assessments are performed to comply with regulatory requirements or industry-specific process safety standards, in many cases the potential for loss of life and property damage is overlooked until a tragedy occurs. Explosion consequence modeling can provide detailed information about the... Learn more
The structure development process begins with creating an ExDAM project file containing the geometry and associated properties of nine data object types:StructuresMapsPeopleLibrary ObjectsPrimary High ExplosivesSecondary High ExplosivesPrimary Vapor CloudsSecondary Vapor CloudsSample Grids Learn more
With structures, people, explosions, and sample grids defined, the explosion models are then executed to predict structure damage, personnel injury, incident and spatial distributions of over pressure, dynamic pressure, and impulse. The execution of an explosion model is referred to as a model run and each model run produces a results file. High explosive model runs produce '.hxr' results files and vapor cloud explosion model runs produce '.vxr' results files. Learn more
Modelers can utilize the ExDAM 3D Extend module to accelerate the structure development process and increase productivity and design efficiency. The 3D Extend module was developed to provide time-saving features to help modelers design and analyze the modeling scenario more quickly when investigating explosion impacts. Learn more
The flying debris caused by damage to frangible structures can be a significant source of injuries in an explosion. Modelers can now utilize the HExFRAG module of BREEZE ExDAM to model these secondary injuries caused by fragmentation. HExFRAG uses the explosion modeling results from the HExDAM module to predict injuries caused by flying debris.The HExFRAG module of BREEZE ExDAM was developed based on research conducted by the Department of Energy on fragmentation damage assessment. The... Learn more
The two traditional explosion consequence modeling techniques have been:Basic phenomenological models that are very cost-effective but provide very simplistic resultsComputational fluid dynamics (CFD) techniques which provide great detail but are time consuming and can be prohibitively expensiveMany facilities are in need of a detailed explosion consequence modeling analysis to identify and mitigate explosion hazards, but require a moderate approach that can provide detailed damage and injury...

The HExDAM damage algorithm is correlated against the Southwest Research Institute pressure-impulse diagrams. The VExDAM model employs Van den Berg's TNO multi-energy method, which uses dimensionless curves of overpressure and pulse duration versus range to predict the resultant overpressure and impulse at each structure. The results were validated in a number of technical papers, written by the developer of the HExDAM and VExDAM models and has been used and validated extensively in other... Learn more
