Modeling Software for EHS Professionals

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 overpressure (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.

Key Features
  • Overhaul of BREEZE ExDAM start page with a new informative layout
  • Import geometric data with 2D and 3D vector/polygon data file formats
  • Use manual editing mode to quickly create a series of connected blocks along a contour line on an XY plane
  • Offers streamlined ribbon bar navigation and numerous tools for efficient model set-up and producing detailed results
  • Provide fully 3D interactive interface that pans, zooms, rotates, and handily performs context-driven operations
  • Provides over 200 CAD-like key strokes and shortcuts
  • Present results in 2D/3D graphical and tabular formats
  • Calculate the blast overpressure and dynamic pressure due to high explosives based on TNT equivalency method
  • Calculate the blast overpressure and impulse due to vapor cloud explosions based TNO Multi-energy method
  • Calculate damage to structures and injury to personnel based upon empirical pressure-impulse (P-I) vulnerability data
  • Simulate blast wave propagation around structures and people, where objects closer to the blast act to shield the blast wave from other objects further away
  • Model secondary or sympathetic explosions triggered by damage or failure during primary blast and calculates additive damage/injury
  • Compatible with previous BREEZE HExDAM and BREEZE VExDAM
Product Tour

BREEZE ExDAM contains the high explosive numerical model, HExDAM, and the vapor cloud explosion numerical model, VExDAM. These numerical models provide a high speed means to predict peak overpressure (OP), dynamic pressure (DP), and impulse (IP) distributions in and around structures and people. These pressure/impulse distributions are a function of the location and strength of an explosion and the shielding that structures and people provide to all other structures and people. For each computed pressure/impulse distribution, the peak incident pressure and impulse on structure and person components is used (via empirical Pressure-Impulse-Damage-Injury data) to predict damage to structure components and injury to person components.

Compared to simple explosion radius techniques, BREEZE ExDAM predicts the shielding effects provided by up-stream structures to down-stream structures. This provides the means to perform more detailed, more precise, and more automated damage/injury consequence analyses. Compared to complex CFD methods, ExDAM provides a computational alternative to full-physical modeling, which is:

  • Easier to perform
  • Less dependent on operator expertise
  • Allows for larger scenario modeling domains
  • Larger numbers of scenario analyses
