ABSTRACT
Research in the area of explosion energy use for controlled demolition of buildings requires thorough knowledge of areas such as the phenomenology of explosion behavior of materials under stress by shock waves, structural dynamics, seismic engineering, etc. The design of these types of processes requires consideration, to the nearest relative degree of danger due to vibration, pressures, tensions in the area affected by the explosion. The estimation of the maximum values of the induced stress has a significant essential importance, and so, the implementation of computerized solutions for experimenting, allows the examination of a large number of scenarios, the limit being mainly subjected by the time allocated for the computerized simulation. In this context, the research in the area, the acquiring of experience and knowledge, and also the validation of the results by comparing them with the previous practical tests and the tests specified in the specialized literature, it becomes a relevant and necessary requirement.
