HAZL performs a single-degree-of-freedom (SDOF) analysis to calculate glass response to a blast loading and provides a debris transport model for predicting fragment trajectory. The program allows modeling of monolithic glass or plastic windows, laminated windows, insulated glass units and windows retrofitted with anti-shatter film. The user inputs window geometry, glazing type, material and thickness, and blast load. With the addition of SFOM and MHGP models, HAZL can predict a hazard rating based on injury severity given a window description, blast parameters and the orientation of a person relative to the window. The models compute the propagation of glass shards, determine which shards would impact the person, and calculate the injury those shard penetrations would cause. A help file is included.
