Abstract
Defence R&D Canada has developed and evaluated military structures for field fortification and camps. Typical structures include: trenches, personnel collective protection, observation posts, tents and storage facilities for water, fuel and ammunition. In support of this work, a Military Blast Effects Expert System (MBEES) have been developed to facilitate the design and deployment of these structures, and to assess their vulnerability to conventional and enhanced blast weapons. MBEES consist of four modules: 1. Explosives and weapons Module: calculates blast properties for a variety of HE, FAE, thermobaric weapons and terrorist improvised explosives. 2. Structures and Scenes Module: provides easy visual set-up of structures and camp layouts, and graphical presentation of the blast loading and structural response. 3. Loading, Response, Design and Vulnerability Module: calculates the blast loading and structural/human response, and evaluates the overall damage to the structure. Blast loading is based on a collection of sub-models for external loading and ingress. These models combine semi-empirical models with an extensive library of computational fluid dynamics results. The structural response algorithms assess blast-induced deformations, including bending, shear and torque deformations. This response is computed using a semi-empirical three-degree-of-freedom model and a structural mechanics based continuous system model. Blast and response models are combined for an overall
