The primary objective of the research was to assess the use of low-cost scanning technologies for 3D scene reconstruction, as well as other non-destructive inspection technologies that could improve the collection of post-blast investigative field evidence. A second objective was to develop the basis of a scientific, physics-based methodology for objective and quantitative determination of charge weight, composition, and epicenter from on-site measurements of the condition of structural and non-structural components damaged by the blast overpressure. In addition, the development and validation of a physics-based methodology could enable automated estimation of charge weight, composition, and epicenter when paired with the high-resolution and accurate 3D scene reconstructions produced by modern 3D scanning tools. The project also pursued the development, verification, and validation of a Blast Dynamics Simulator, based on an implementation of the Applied Element Method to enable prediction of component behavior through fracture, fragmentation, and development of a debris field. The project succeeded in providing a foundation for introducing 3D scanning and reconstruction tools for documentation of post-blast forensic scenes, specifically the reconstruction and profiling of blast-induced damage to structural and non-structural building components. Over the long term, the improved scene documentation tools assessed in this project could facilitate the development of a database of scientific data from post-blast investigations that may produce data-driven heuristics for forensic benchmarking and advanced empirical study of explosive effects on conventional building structures. The initial development of a Blast Dynamics Simulator in this project can assist in promoting post-blast forensic investigations. 7 references, 1 table, and 14 references
