Propagacao de Uma Onda de Explosao Aerea e Seu Efeito Sobre uma Estrutura (Air Explosion Shock Waves: Propagation and Action on a Structure)

摘要

The work constitutes a first approach to the design of a lumped model for the description of the air explosion wave generation, propagation and structural interaction mechanisms, with special concern about the second and the third. The model allows for the determination of incident wave parameters and structural response for given explosion and neighboring structure characteristics. An analysis is made of the theoretical subjects underlying the model, such as Compressible Fluid Mechanics, Dimensional Analysis and Structural Dynamics. Results are presented of experimental tests carried on to help model's design. Model's structure and implementing are described, so as its application to the case of several buildings under loading due to a given explosion.
